15. Long answer question III

 

a. The first stage of aerobic respiration is glycolysisFermentation .

b. Both aerobic and anaerobic respiration begins with the process called kreb cycleglycolysis.

c. The term glycolysis means glucose splittingglucose bonding.

d. One molecule of 6 carbon glucose is broken down into two molecules 3 carbon succinic acid 3 carbon pyruvic acid  of during glycolysis.

e. Glycolysis occurs in the cytoplasm of the cellnucleoplasm of the cell.

f. The second stage of cellular respiration is the fermentationKrebs cycle.

g. The Krebs cycle occurs in the Inner mitichondrial membranemitochondrial matrix.

h. Krebs cycle was discovered by Sir Hans KrebsSir Hairston Krebs.

i. The two molecules of pyruvic acid produced in the glycolysis enter the mitochondriagolgi apparatus after glycolysis.

k. Krebs cycle is also known as the Tricarboxylic acid cycle Tetracarboxylic acid cycle .

l. The third stage of aerobic respiration is the fermentationelectron transport chain.

m. The electron transport chain is a system of electron carrier complex found on the outer membrane inner membrane  of the mitochondria.

n. During the electron transport chain, the \(NADH_2\) and \(FADH_2\) molecules produced in the glycolysis and Krebs cycle are oxidised to \(NADH\) and \(FADH\)\(NAD^+\) and \(FAD^+\) to release energy via electrons. As these electrons move through the system of the electron chain, they release the energy that the ADP traps to synthesise ATP, which is known as oxidative pyrohydrolysisoxidative phosphorylation as a phosphate group is added to ATP. \(O_2\) serves as the final acceptor electrons and gets reduced to water.
