Starting with one molecule of isocitrate and ending with fumarate the maximum number of ATP molecules that could be made through substrate-level phosphorylation is one
Cells primarily employ adenosine triphosphate, or ATP, as their source of energy. It can be broken down to liberate the energy held in its phosphate bonds, which have a lot of energy. In the first stage of the citric acid cycle, isocitrate is changed into alpha-ketoglutarate, which causes substrate-level phosphorylation to produce one molecule of NADH.
The remaining phases of the citric acid cycle use the NADH and FADH2 created during the cycle to make ATP through the electron transport chain rather than substrate-level phosphorylation. Therefore, one isocitrate molecule can only be converted into one ATP molecule through substrate-level phosphorylation.

which element forms a 3+ ion that has the electron configuration [kr]4d6 ?
The element Rhodium (Rh) has the electron configuration [Kr]4d⁶[K r] ⁴d⁶ and, as a result, forms a 3⁺ ion with that exact same name.
Rhodium, which has the chemical symbol Rh and atomic number 45, is an element. It is an extremely uncommon transition metal that is white in color, exceedingly hard, and resistant to corrosion. The platinum group metals include this precious metal. Naturally occurring 103Rh is the only isotope of this element.
Rarely does rhodium occur as a chemical compound in minerals like bowieite and rhodplumsite, but it does so frequently as a free metal or an alloy with other metals. It is extremely rare and therefore extremely expensive.
Similar to the other platinum group metals, rhodium can be mined from platinum or nickel ores. William Hyde Wollaston found it in 1803 in one of these ores and gave it the name "rose" after one of its chlorine derivatives, which is a deep pink.

in the early 1960s, radioactive strontium-90 was released during atmospheric testing of nuclear weapons and got into the bones of people alive at the time. if the half-life of strontium-90 is 27 years, what fraction of the strontium-90 absorbed in 1962 remained in people's bones in 1990?
The fraction of the strontium-90 that remained in people's bones in 1990 can be determined by using the formula:
N(t) = N0 * (1/2)^(t/T)
Where N(t) is the remaining amount of strontium-90 in people's bones at time t, N0 is the initial amount absorbed in 1962, t is the time elapsed (1990 - 1962 = 28 years), and T is the half-life of strontium-90 (27 years).
So, N(1990) = N0 * (1/2)^(28/27) = N0 * (1/2)^1 = N0 * (1/2) = 0.5 * N0
Therefore, the fraction of strontium-90 that remained in people's bones in 1990 is 1/2 or 0.5.

Explain why the Vmax of the reaction is much lower with non-competitive inhibitor than reaction without inhibitor or with competitive inhibitor at high substrate concentrations.
The Vmax of the reaction is much lower with non-competitive inhibitor than reaction without inhibitor or with competitive inhibitor at high substrate concentrations because of noncompetitive inhibitor can only bind to an enzyme with or without a substrate at several places at a particular point in time
The substrate still binds to the enzyme in the presence of noncompetitive inhibitors. In fact, the binding of the substrate and inhibitor to the enzyme is completely unaffected by one another. The enzyme, however, is unable to catalyze the reaction to produce a product when the inhibitor is attached. Noncompetitive inhibition works by lowering the quantity of active enzyme molecules available to carry out a process.
In non-competitive inhibition, a different site on the enzyme is the spot where the inhibitor molecules interact with the substrate molecules rather than the active sites on the enzyme surface. As a result, there are less enzyme molecules available to catalyze the reaction. Thus, V m an x is decreased. Because of this, extra substrate cannot entirely overcome the non-competitive inhibitors. As a result, the reaction's V max decreases.

(6) There are only two elements named after women. Who are the two women? What are the names and the atomic numbers of the elements named after them? What was each woman's contribution to science?
Curium (Cm) and Rhenium are the two elements with female names (Re).
How were the two elements named after women?After Marie Curie, a pioneering researcher in the realm of radioactivity, the element curium, with atomic number 96, was named. She was the first person to receive two Nobel Prizes, one each in physics and chemistry, and her work on the discovery of radium and polonium contributed to the advancement of X-ray technology and the development of cancer therapies.
Rhenium, an element with the atomic number 75, was given its name in honour of Ida Tacke-Rhenium, a German scientist who made the discovery of the substance alongside her husband in 1925. The element was found and isolated by her, and it has since been widely employed in high-temperature alloys, catalysts, and electronic parts.
What was each women's contribution to science?Both of these women made significant contributions to science, and the naming of these elements pays tribute to them. They were pioneers in a male-dominated industry, and their contributions have had a lasting influence on science and technology.

consider the molecule hclo3.what is the electron domain geometry of the central chlorine atom in this molecule? tetrahedralwhat is the molecular geometry of the central chlorine atom in this molecule? tetrahedralanswer 1:tetrahedral answer 2:tetrahedral
Electron domain geometry of the central chlorine atom in this molecule has one lone pair on the core Cl atom, due to it's existence the structure of HClO3 has a trigonal pyramidal.
Is trigonal planar HClO3?Trigonal planar bond angle is 1200. But because there are numerous double bonds and lone pairs, the bond angle around the core Cl atom is less than 1200.
What are geometries for electron domains?Two single bonds and two nonbonding lone pairs make up the four domains of H2O. The steric number is another name for the electron domain. The configuration of the electron domains that surround the primary atom in a molecule or ion is known as the electron domain geometry.
What class of substance is HClO3?The formal precursor of chlorate salts is chloric acid, often known as HClO3, which is an oxoacid of chloride.

how can you determine if an anion will act as a weak base? write a generic equation showing the reaction by which an anion, a-,acts as a weak base.
A- + H2O -> HA + OH-, anion that acts as the nucleophile of a dangerous chemical is pH- neutral, according to the question, anion that is organic compound with the formula of such a weak base is itself a weak base.
With an example, what is weak base?The fundamental elements that are unable to completely oxidise in water are known as weak bases. Ammonia is one substance that is a weak base. When NH3 is dissolved by water, some of it interacts with the water vapor and breaks down into ammonium ion and hydroxide anions.
NaOH: Is it a weak base?NaOH totally separates from water to produce Na+ and OH. Because all of the [OH] in NaOH is in the solution as [OH] that is ready to receive protons, it is regarded as a strong base.
