CELL RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What energy is needed by organisms during the cell respiration?
A
Mechanical energy
B
Chemical energy
C
Light energy
D
Potential energy
Explanation: 

Detailed explanation-1: -ATP. Specifically, during cellular respiration, the energy stored in glucose is transferred to ATP (Figure below). ATP, or adenosine triphosphate, is chemical energy the cell can use.

Detailed explanation-2: -Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.

Detailed explanation-3: -Organisms mainly use the molecules glucose and ATP for energy . Glucose is a compact, stable form of energy that is carried in the blood and taken up by cells. ATP contains less energy and is used to power cell processes.

Detailed explanation-4: -Cellular respiration is a metabolic pathway that uses glucose to produce adenosine triphosphate (ATP), an organic compound the body can use for energy. One molecule of glucose can produce a net of 30-32 ATP.
