Question

The process by which the energy of glucose is released under aerobic respiration was discovered by:
A. Hopkins
B. Lister
C. Krebs
D. Pasteur

Answer 1

Hint: Aerobic respiration is the process by which glucose energy is released in the presence of oxygen. Aerobic respiration degrades glucose and mixes the degraded products with oxygen to produce water and carbon dioxide. Carbon dioxide is a waste product of anaerobic respiration because cells do not need it.

Complete explanation:
Option A Hopkins: Hopkins was awarded the Nobel Prize for his discovery of the growth-stimulating vitamins.
Option A is not correct.
Option B Lister: Sir Joseph Lister who was the founder of antiseptic medicine and a pioneer in preventive medicine. He pioneered the use of carbolic acid to sanitise surgical tools and cleanse wounds.
So, Option B is not correct.
Option C Krebs: German born British biochemist Hans Krebs, who received the \[1953\] Nobel prize for physiology or medicine for the discovery in living organisms of the series of chemical reactions known as tricarboxylic acid cycle also called Citric Acid Cycle. These reactions involve the conversion in the presence of oxygen or substances that are formed by the breakdown of sugars, fats and proteins components to carbon dioxide water and energy rich compounds.
Option C is correct.
Option D Pasteur: Louis Pasteur discovered that microorganisms cause fermentation and disease. He originated the process of pasteurization, saved the beer, wine and silk industries in France; and developed vaccines against anthrax and rabies.
So, option D is not correct.

Hence, Option C) is the correct answer.

Note:
Under aerobic conditions, one molecule of glucose converts into two molecules of pyruvate or pyruvic acid, yielding energy in the form of two net molecules of ATP. What products produced during aerobic respiration are determined by the presence of oxygen. Carbon dioxide water and ATP are produced during aerobic respiration and during anaerobic respiration lactic acid ethanol and ATP are created.
