Question

Which of these processes would be catabolic) building muscle building fat conversion of glucose to glycogen glycolysis Metabolic products of carbohydrate and fatty acid metabolism enter the Krebs Cycle through which intermediate? ATP NAD Acetyl-CoA FADH_2 The most commonly used Biochemical oxidizing agent is NAD FAD NADH NADPH The most commonly used Biochemical reducing agent is: NAD FAD NADH NADPH An energetically unfavorable reaction may proceed if: It's enzyme is allosterically activated Its enzyme has a low Km its enzyme has a high V_max it is coupled to an energetically favorable reaction Which of these phosphates yield more energy upon hydrolysis than ATP? sodium phosphate glucose-6-phosphate creatine phosphate ADP Which of these compounds would yield the most energy upon oxidation? CH_3CH_3 CH_3CH_2OH CH_3CHO CH_3CO_2H In oxidative phosphorylation, ATP production is coupled to the oxidation of: NADH NADPH lactate pyruvate

Explanation / Answer

Please find the answers below:

Part 1: D (Catabolic process are those in which a bio-molecule/compound is broken down to release energy. Building of muscles and fats and coversion of glucose to glycogen are all anabolic processes. Glycolysis is catabolic in nature since it releases energy by breakdown of sugars)

Part 2: C (Acetyl coenzyme A is the major intermediate formed during metabolic processes which gets incorporated into Kreb's cycle to release energy and secondary by-products)

Part 3: A (An oxidizing agent is a compound which itself undergoes reduction or addition or hydrogen or addition of electrons during a process. NAD represents the most common biochemical oxidizing agent since it is the most abundant compound incorporated in energy-generation processes such as electron transport chain, Kreb's cycle, glycolysis etc.)

Part 4: D (A reducing agent is a compound which itself undergoes oxidation or loss of electrons or loss of hydrogen during a process. Although both NADPH and NADH are abundant enough, but NADPH is highly abundant in cytosol whereas NADH is found more concentrated in mitochondria. Thus, NADPH is more abundant than NADH)
