an enzyme is specific. this means

Answers

Answer 1

Enzymes are said to be specific because an enzyme binds to only one or one group of substrates for its activity.

The enzyme's specificity is a property that indicates how restricted the enzyme is in its substrate selection; There would only be one substrate for a completely unique enzyme. Specificity is the capacity of an enzyme to select a specific substrate from a variety of chemically similar compounds. Specificity is a molecular identification process due to the complementary structural and conformational properties of the enzyme and substrate. Since the specific substrate must fit into the enzyme's active site before catalysis can take place, only well-designed molecules can be enzyme substrates; An enzyme will frequently react with a single naturally occurring molecule or substrate.

Why might it not always be possible to determine the reactants and the products in a reaction? Explain your answer in terms of chemical equilibrium.

Answers

It might not be possible to always determine the reactants and products in reactions because reactants can be products just as products can be reactants in some reactions.

What are reversible reactions?

Reversible reactions are reactions that proceed in both forward and backward directions.

The forward reaction is for the synthesis of products while the backward reaction synthesizes the reactant back as they are known in non-reversible reactions.

For example, consider this reaction: [tex]A + B < --- > C + D[/tex]

In the forward reaction, A and B are acting as the reactant while C and D are the products. In the backward reaction, C and D are the reactants while A and B are the product.

In reversible reactions, the forward reaction proceeds, but as soon as products are formed on the other side, both forward and backward reactions occur simultaneously, although at an unequal rate.

Reaction continues until a chemical equilibrium is reached. Both the forward and backward reaction proceeds at an equal rate.

Approximately 30 - 32 molecules of ATP are produced from the complete oxidation of one molecule ofglucose (C6H12O6) in aerobic cellular respiration. Explain reasons why the number of ATP is not knownexactly

Answers

One glucose molecule produces 4 ATP, 2 NADH, and 2 pyruvate molecules during glycolysis. Although 4 ATP molecules are produces in the second half, the net gain of glycosis is only 2 ATP because 2 ATP molecules are used in the first half of glycolysis. If the cell cannot catabolize the pyruvate molecules further via the citric acid cycle, it will harvest only 2 ATP molecules from one molecule of glucose.

Glycolysis is the sole source of ATP. If glycolysis is disrupted, the RBC fail their ability to control their Na-K pumps that need ATP to function, and eventually, they die. If the second half of glycolysis slows or stops in the absence of NAD+ or when NAD+ is unavailable, RBC will not produce a sufficient number of ATP in order to survive.

The number of ATP has been estimated between 35 to 30. The total number of ATP is not known exactly due to variance in the degree of coupling between the flow of protons through the ATPase and electron transport ATP which is the energy currency of the cell.

what does food and water affect homeostasis of a population

Answers

Food and water affect the homeostasis of a population because they are required nutrients to maintain the state of internal equilibrium in biological systems.

What are homeostasis conditions?

Homeostasis conditions refer to all inputs from the surrounding environment that are required for biological systems in order to maintain the state of internal equilibrium, which is fundamental to sustaining life in organisms.

Water and foods are fundamental to maintaining the state of internal equilibrium or homeostasis conditions because they are required to carry out metabolic activities such as reproduction, growth, differentiation, etc, thereby the absence of these nutrients lead to the death of biological systems.

Therefore, with this data, we can see that homeostasis conditions are associated with the state of equilibrium of biological systems, which require the input of nutrients such as foods and water in order to carry out metabolic activities.

Which process (es ) contribute to the proton gradient that powers ATP synthase in chloroplasts ? Choose ALL correct answers A proton pump uses light energy to move protons into the thylakoid space Protons are produced when water is split Protons are pumped into the thylakoid space using the energy from an electron transport chain Protons are produced when NADP + is reduced

Answers

Proton gradients are essential for chloroplast function. The light-induced gradient across thylakoid membranes is required for ATP synthesis.

Does ATP synthase pump protons?

The ATP synthase enzyme is reversible and can also function as a proton pump by coupling ATP hydrolysis to proton translocation. Each respiratory enzyme employs a unique strategy for proton pumping.

The light energy is used to separate an electron from PSII, causing it to cascade through the electron transport chain. Along with the electron transfer, a proton gradient across the thylakoid membrane is established, with a higher concentration of protons and a lower pH in the thylakoid lumen.

Therefore, the proton pump uses light energy to move protons into the thylakoid space.

Why is water cycle a biogeochemical cycles?

Water and components like carbon and nitrogen are recycled, whereas energy moves through an ecosystem. The environment is continually recycling nutrients and water. A biogeochemical cycle is the term used to describe the continuous recycling of a chemical element or water within an ecosystem. Both living creatures (biotic components) and nonliving objects (abiotic elements) in the ecosystem are involved in this recycling process. Water and other chemical elements are continuously transferred through living things to non-living things and back again through biogeochemical cycles. The water cycle, carbon cycle, and nitrogen cycle are three significant biogeochemical cycles.

The biogeochemical cycle that recycles water is the water cycle.

Albedo is the reflectivity of a surface. Surfaces that are very reflective, have high albedo. Which BEST describes the historical albedo of the earth?

A. More than 50 percent
B. Less than 50 percent
C. Exactly 100 percent
D. Exactly o percent​

Answers

The correct answer is option B.

When the light hits the Earth, a particular amount of light is reflected back. This reflected rays of light is called albedo.

There are few places through which the light gets reflected and these are the lighter places.

The surface that reflects the most are lighter places like ice and the places that doesn't reflect are the dark places like soil.

The best historical albedo was seen in 1970s. During that period, the reflection was high and also during winters the amount of ice formation was also good.

After that due to the global warming, the percentage went down. Albedo is the reflecting light and if the light isn't trapped then the temperature tends to come down. We can say, the higher the albedo of the surface, the cooler will be the surroundings.

The best percentage of albedo in 1970s was around 30% which was historical albedo of the Earth.

Oxygen and glucose are transformed into water and carbon dioxide during cellular respiration. By-products of the process include carbon dioxide, water, and ATP, which is turned into energy.

What are Cellular Respiration and Photosynthesis?Commonly used notation for photosynthesis is: 6CO2 + 6H2O C6H12O6 + 6O2. This means that the products, a sugar molecule and six oxygen molecules, are produced when light energy, which is harvested as chemical energy during photosynthesis, is converted from the reactants, six carbon dioxide molecules and six water molecules, into a sugar molecule and six oxygen molecules. The byproduct is the emission of oxygen. In the process of breaking down glucose during cellular respiration, oxygen is consumed, which also produces heat and chemical energy.

There are many cells we can see with our unaided eyes in the ovum.

The human eye can see objects as small as 100 microns. Objects below 100 microns cannot be seen with the eye. Cells in our bodies are 10 microns in size and cannot be seen with the eye. Eggs, like single cells, can be seen without a microscope. In all mammals, the egg is the only cell visible to the human eye.

Cells are so small that they are usually invisible to the eye. As we age, the vitreous jelly-like substance in the eye liquefies and shrinks.
