NEET BIOLOGY

Detailed explanation-1: -Answer and Explanation: The mitochondrion is the organelle responsible for producing usable energy for the cell, therefore the answer is a. Mitochondria are often referred to as the powerhouse of the cell because they are responsible for producing the bulk of the cell’s ATP via aerobic respiration.

Detailed explanation-2: -Mitochondria Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Detailed explanation-3: -Because the energy to drive ATP synthesis in mitochondria ultimately derives from the oxidative breakdown of food molecules, the phosphorylation of ADP to form ATP that is driven by electron transport in the mitochondrion is known as oxidative phosphorylation.

Detailed explanation-4: -Mitochondria convert chemical energy, in the form of a chemical called adenosine triphosphate or ATP for short. ATP is an energy currency that every cell in our body can use.

Detailed explanation-5: -Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration.
