Importance Of ATP

Question 1

Explain the process of chemiosmosis

Answer 1

Protons pass through ATP synthetase.
Flow of protons generate an electrochemical gradient
This drives the phosphorylation of ADP to form ATP

Question 2

Compare mitochondrial and chloroplast membranes?

Answer 2

In mitochrondria protons flow from the intermembrane space into the matrix
In chloroplasts protons flow from the thylakoid space into the stroma

Question 3

Why is ATP the universal currency?

Answer 3

Used for all reactions in cells
Easily transported and releases energy efficiently (30.6KJ)
Single enzyme required
