An enzyme, citrate synthase, in the krebs cycle is inhibited by atp. this is an example of all of the following except:
a. allosteric inhibition
b. noncompetitive inhibition
c. competitive inhibition
d. feedback inhibition

The correct answer is d. feedback inhibition.

Explanation:

The Krebs cycle produces ATP, so in this case, it's inhibited by the product. This kind of inhibition is called feedback because there's positive feedback in the process and it becomes a regulation method; when the citrate enzyme perceives the excess of product, the process stops because there's enough already in the means.

answer: populations of walruses and polar bears will decline

explanation:

you put it

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.
