Remember that glycolysis produces two pyruvic acid molecules per glucose molecule along with two of the hydrogen-carrying nadh molecules. remember also that the krebs cycle produces nadh as well as another hydrogen carrier called fadh . it is important to know that during the electron transport chain, when each nadh gives up electrons and hydrogen ions, there is enough of a potential energy change to make three atp molecules. when each fadh 2gives up electrons and hydrogen ions, there is enough of a potential energy change to make two atp molecules. 20. fill in the chart below to calculate the total amount of atp produced from the breakdown of each glucose molecule during the three steps of cellular respiration. number of atp produced from one glucose molecule number of h-carriers produced from one glucose molecule nadh fadh 2 glycolysis krebs cycle electron transport chain
Answers
Glycolysis produces 2 ATP and 2 NADH, Krebs cycle produces 2 ATP, 6 NADH, and 2 FADH2, and ETC generates 28-34 ATP.
Step of Cellular Respiration Glycolysis has number of ATP Produced is equal to 2 and number of H-Carriers Produced is 2 NADH, Step of Cellular Respiration Krebs Cycle has number of ATP Produced is equal to 2 and number of H-Carriers Produced is 6 NADH, 2 FADH2 and Step of Cellular Respiration Electron Transport Chain has number of ATP Produced is equal to 28-34 (depending on cell type).
The exact number of ATP molecules produced in the electron transport chain can vary depending on the cell type and conditions. The range given (28-34) is a typical estimate for eukaryotic cells.
The breakdown of glucose during cellular respiration involves three main steps: glycolysis, the Krebs cycle, and the electron transport chain. These steps produce energy in the form of ATP molecules and hydrogen carriers, such as NADH and FADH2. Glycolysis produces 2 ATP and 2 NADH, while the Krebs cycle produces 2 ATP, 6 NADH, and 2 FADH2. During the electron transport chain, the hydrogen carriers release their electrons and protons to generate a proton gradient, which is used to make a large amount of ATP.

A species of bird has migrated to an island where their population is growing rapidly due to a lack of predators. Identify three limiting factors to the population size, and describe the effect of each.
Answers
Answer:
A species of bird that has migrated to an island where their population is growing rapidly due to a lack of predators may experience the following limiting factors:
Food resources: One limiting factor could be the availability of food resources. If the bird population grows too quickly and consumes all of the available food, the population may be limited by a lack of food. This can result in reduced growth, starvation, and decreased survival rates.Disease: Another limiting factor could be the presence of disease. If a disease outbreak occurs, it could reduce the population size and limit its growth.Breeding habitat: The bird population may also be limited by the availability of suitable breeding habitat. If the island becomes overcrowded, the birds may not have access to enough space to build nests, mate, and rear their young. This could result in decreased breeding success, reduced population growth, and ultimately a decrease in population size.In conclusion, the growth of the bird population on the island may be limited by the availability of food resources, the presence of disease, and the availability of suitable breeding habitat. These factors can have a significant impact on the population size and its ability to sustain itself over time.

In which two processes do cells make a small amount of ATP for every

A. Glycolysis
B. Fermentation
C. The electron transport chain
D. The Krebs cycle
SUBMI
Answers
Glycolysis and Kreb's cycle are two processes in which cells make a small amount of ATP for every glucose molecule split in two.
Describe glycolysis.
The process by which glucose is broken down to provide energy is known as glycolysis. It generates two pyruvate molecules, ATP, NADH, and water. There is no need for oxygen throughout the process, which occurs in the cytoplasm of a cell.
An overall net of two ATP molecules will be created during fermentation and glycolysis. To prevent glycolysis from ceasing, fermentation will produce 2 ATP, and glycolysis will produce 2 ATP through substrate level phosphorylation. There is no electron transport system involved in fermentation, and no ATP is produced during the fermentation process itself. Two ATP, six NADH +H+, and two FADH2 were created during the Krebs cycle. Due to the two pyruvic acid molecules that enter the system for every glucose molecule, two ATP molecules are produced.

The deer density in 1923 was one deer per 8 acre. Pet capita rate of growth of deer population is influenced by carrying capacity (K).
Population distribution is the spatial arrangement of individuals of a given species in a particular area at a given time. They may be influenced by factors like resource availability, climate, topography, vegetation, etc. The growth of mule deer population in terms of carrying capacity can be explained with the help of logistic growth.
In logistic growth, the per capita rate of growth of a population gets smaller as the population approaches a maximum number influenced by the number of limited resources available. This rate is known as the carrying capacity, denoted by K. The initial growth in logistic growth is exponential, where this carrying capacity first increases.

The ability to form a covalent bond between its amino and carboxyl groups.
What is covalent bond?
A covalent bond is a type of chemical bonding that occurs between two non-metallic atoms. This type of bond is formed when the outer valence electrons of each atom are shared between the two atoms, resulting in the formation of a chemical bond. Covalent bonds are strong and can be found in a variety of molecules, including water and carbon dioxide. This type of bond is often found in many organic molecules, including proteins, carbohydrates, and DNA. Covalent bonds are important for the stability of many molecules and are responsible for the unique properties of many substances. Covalent bonds can be single, double, or even triple bonds depending on the number of electrons shared by each atom. In general, the strength of a covalent bond is determined by the number of electrons shared between the two atoms, as well as the distance between them.

These gases were used to create Earth's primitive oceans in the experiment. In the experiment, the gases were placed in a closed system, and an electric spark was used to simulate lightning, which was believed to have been abundant on the early Earth. After running the experiment for a week, the liquid pool contained a variety of organic compounds, including amino acids, which are the building blocks of proteins.

To construct an accurate cladogram, it is important to use multiple sources of data, such as physical traits, DNA sequences, and fossil records. An outgroup species is a species that is closely related to the group being studied but not a part of it. By choosing an appropriate outgroup species, scientists can better identify shared characteristics that are unique to the group being studied and therefore construct a more accurate cladogram.
