Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which process takes place in the presence of oxygen and produces nearly 20 times as much as ATP as glycolysis alone?
A
photosynthesis
B
lactic acid fermentation
C
aerobic respiration
D
alcoholic fermentation
Explanation: 

Detailed explanation-1: -Today, most organisms make ATP with oxygen. They follow glycolysis with the Krebs cycle and electron transport to make more ATP than by glycolysis alone. Cellular respiration that proceeds in the presence of oxygen is called aerobic respiration.

Detailed explanation-2: -Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.

Detailed explanation-3: -Aerobic Respiration – if enough oxygen is present, pyruvate enters this pathway. Yields nearly 20 times more ATP than glycolysis alone.

Detailed explanation-4: -Aerobic Respiration: It is the process of cellular respiration that takes place in the presence of oxygen gas to produce energy from food. This type of respiration is common in most of the plants and animals, birds, humans, and other mammals. In this process, water and carbon dioxide are produced as end products.

Detailed explanation-5: -The stage that produces most of the ATP during cellular respiration is the electron transport system (ETS).
