Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following best describes the function of mitochondria?
A
they convert energy from food molecules into energy the cell can use
B
they store energy from sunlight
C
they produce nucleic acids that release energy
Explanation: 

Detailed explanation-1: -Known as the “powerhouses of the cell, ” mitochondria produce the energy necessary for the cell’s survival and functioning. Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes.

Detailed explanation-2: -Mitochondria performs the function of energy generation. It helps in production of molecules called ATP (adenosine triphosphate) which help in generating energy. This energy is utilised by other parts of the cell for performing their functions. Hence, mitochondria is also called “powerhouse of the cell".

Detailed explanation-3: -Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria.

Detailed explanation-4: -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-5: -Which statement describes the role of a mitochondrion in providing a body with energy? It stores glucose that is taken from food so that respiration can happen later.
