You are studying the enzyme kinetics of enzymes in the Kreb cycle. You add a molecule to the mixture that appears to act as a co

mpetitive inhibitor of one of the enzymes. At first, you cannot tell which enzyme is inhibited, but you can tell that it is bound to the inner mitochondrial membrane. Can you guess which Kreb cycle enzyme you have inhibited and how do you know?

Answer: Succinate dehydrogenase

Explanation: succinate dehydrogenase or Complex II or succinate-coenzyme Q reductase is an enzyme complex involved in citric acidic cycle, bound to the inner mitochondrial membrane of mammalian mitochondria and cell membrane of many bacterial cells. It is the only enzyme that participates in both the citric acid cycle and the electron transport chain. This enzyme catalyzes the oxidation of succinate to fumarate with the reduction of ubiquinone to ubiquinol, reaction occurs in the inner mitochondrial membrane by coupling the two reactions together.

Ludmilka [50]

Answer:

Phosphorylation within the nuclear export signal interferes with the function of the  signal.

Explanation:

In biochemistry, phosphorylation is the addition of a phosphate group (PO4) to a protein or other molecule. Phosphorylation is a major player in protein regulation mechanisms, preventing protein-catalyzed reaction product from accumulating in the body causing problems.

However, in some cases phosphorylation may cause nuclear accumulation of a protein in the nucleus of the cell. An example of this is the protein shown in the question above. In this case, phosphorylation in the nuclear export signal interferes with the signal function, resulting in protein accumulation in the nucleus.

Which one of the following is likely to be associated with a loss of genetic diversity in a local population of a species?
Vikentia [17]

No information is available regarding the options of the given question. The answer will contain all the factors that might cause the loss of genetic diversity.

Answer:

Genetic diversity may be defined as the different genetic constitution is present in the population. Mutation, natural selection results in evolution that increases the genetic diversity.

The genetic diversity can be lost in the local population by the different mechanisms. The sudden loss of the genetic diversity can occur through the natural calamity. The introduction of the new allele and its selection through many generation might result in the loss of genes present already in the population. Increase in the homozygosity can also cause the loss of genetic diversity.
