Question

Which of these statements is incorrect
A) glycolysis operates as long as it is supplied with NAD that can pick up hydrogen atoms.
B) enzymes of the TCA cycle are present in the mitochondrial matrix.
C) oxidative phosphorylation takes place in the outer mitochondrial membrane.
D) glycolysis occurs in the cytosol.

Answer 1

Hint: every living organism that you can see around breeds and respire to live. Despite the vast diversity of organisms, the biochemical reactions that are part of the respiratory process are more or less the same in every organism. Glycolysis is a process that consists of two phases that is an energy-absorbing phase and an energy-releasing phase.

Complete answer:
If you were to hand out a molecule of glucose to the friendly lactobacillus acidophilus the bacterium that converts milk into curd the metabolism would be quite different from that of yours. Nevertheless, the first step of the process would remain pretty much the same. Both you and acidophilus would need to first split the glucose molecule into two parts through the process of glycolysis. This process mainly consists of two phases energy absorbing process and energy-releasing process in the form of ATP. Glycolysis is a series of reactions in which glucose molecules split into two, three-carbon molecules called pyruvate and releases energy in the form of ATP. It is a very ancient pathway and it is the first stage of cellular respiration.
Like all metabolic processes, glycolysis follows the distinct Pathways which is catalyzed by various types of enzymes. It starts in the cytosol of the cell. During this process, glucose is broken down into two molecules of pyruvate. Glycolysis operates as long as it is supplied with anybody that can pick up hydrogen atoms that are released during the oxidation of PGAL(phosphoglyceraldehyde). enzymes of the TCA cycle are present in the mitochondrial matrix space. Oxidative phosphorylation takes place in the inner mitochondrial membrane.
Thus, the answer is option C: oxidative phosphorylation takes place in the outer mitochondrial membrane.

Note: The respiratory quotient is a dimensionless number that is used in BMR calculation. RQ can be determined from the ratio of produced carbon dioxide to consumed oxygen. using respirometer RQ you can be measured.
