RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A decrease in the amount of oxygen available will ____
A
not have an effect on the amount of energy produced during cellular respiration
B
decrease the amount of glucose produced during cellular respiration
C
cause the amount of water produced during cellular respiration to increase
D
decrease the amount of energy produced during cellular respiration
Explanation: 

Detailed explanation-1: -Anaerobic metabolism and loss of adenosine triphosphate (ATP) occur when oxygenated blood is not delivered to cells, resulting in cellular membrane breakdown and anaerobic metabolism.

Detailed explanation-2: -Without oxygen, organisms can split glucose into just two molecules of pyruvate. This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules.

Detailed explanation-3: -Oxygen is required in the cellular respiration in the electron transporter chain. It serves as the final electron acceptor of the electron transport chain facilitating the movement of electrons down the chain hence producing the ATP or adenosine triphosphate.

Detailed explanation-4: -Answer: Solution: The energy released during respiration is used for carrying out various life processes. Some of the energy liberated during the breakdown of the glucose molecule is in the form of heat, but a large part of it is converted into chemical energy released by these ATP molecules.
