Which of the following option is correct regarding the ATP Synthase

1. ATP Synthase Has Two Functional Domains, Fo and F1

2. It Catalyzes the formation of ATP from ADP and Pi, driven by the flow of protons from the P to the N side of the membrane.

3. ATP synthase produces ATP as protons diffuse back through it from the lumen into the stroma.

4. The molecular structure of the mitochondrial ATP synthase has been determined by X-ray crystallography.

Some of the statements regarding competitive inhibition are given below

a)  The effect of a competitive inhibitor depends on the inhibitor concentration, the substrate       concentration and the relative affinities of the substrate and the inhibitor for the enzyme.

b) if the substrate concentration is low, the degree of inhibition will be great.

c) the substrate concentration is high, then the degree of inhibition will be marked low

d) non-competitive inhibitor can combine with an enzyme molecule to produce a dead-end complex
