1. A
Krebs cycle aur tricarboxylic acid cycle is a process which leads to the formation of many fatty acid intermediates and many molecules of ATP. It takes place in mitochondrial matrix. It begins with the condensation of acetyl coenzyme a with oxaloacetate to form citric acid.
2. A
Glycolysis is the process of breakdown of one molecule of glucose into two molecules of pyruvic acid. It ends with the formation of two molecules of ATP and two molecules of NADH. There is no decarboxylation step in this process.
3. B
Maximum number of ATP molecules are formed by oxidative phosphorylation of hydrogen electron Carriers produced in tricarboxylic acid cycle.
4. D
Glycolysis occurs in the cytoplasm of Every cell. It is a common step for aerobic and anaerobic respiration.
5. C
During citric acid cycle, hydrogen ions and electrons are released from every fatty acid intermediate and passed onto high energy electron carriers (NADH, FADH2). This electron Carriers then donate their electrons to electron transport system taking place in inner mitochondrial membrane for the generation of ATP.
