4.1 Importance of ATP
You should be prepared to discuss...
(a) The importance of chemical energy in biological processes. The central role of ATP as an energy carrier and its use in the liberation of energy for cellular activity. Structure of ATP.
(b) The synthesis of ATP by means of a flow of protons through the enzyme ATP synthetase. Chemiosmosis and electrochemical gradient. The similarity between mitochondrial and chloroplast membrane function in providing a proton gradient for ATP synthesis.
(c) The maintenance of the proton gradient by proton pumps driven by electron energy. The alternate arrangement of pumps and electron carriers to form the electron transport chain. (Names of proton pumps and electron carriers in the electron transport system are not required).
