Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organelle is the primary site of ATP synthesis in eukaryotic cells?
A
lysosome
B
vacuole
C
mitochondria
D
Golgi apparatus
Explanation: 

Detailed explanation-1: -The mitochondrion is referred to as the ‘power house’ of the cell, because it is responsible for the synthesis of the majority of ATP under aerobic conditions. The inner membrane of the mitochondrion contains the components of the electron transport chain.

Detailed explanation-2: -Human mitochondrial (mt) ATP synthase, or complex V consists of two functional domains: F1, situated in the mitochondrial matrix, and Fo, located in the inner mitochondrial membrane. Complex V uses the energy created by the proton electrochemical gradient to phosphorylate ADP to ATP.

Detailed explanation-3: -Mitochondria are the major site of oxidative metabolism, and hence ATP synthesis, in eukaryotic cells.

Detailed explanation-4: -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).
