ATP ADENOSINE TRIPHOSPHATE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where does the cellular process occur the most?
A
Mitochondria
B
Nucleus
C
Prokaryotic Cell
D
Cell Membrane
Explanation: 

Detailed explanation-1: -The mitochondrion performs most cellular oxidations and produces the bulk of the animal cell’s ATP. The mitochondrial matrix contains a large variety of enzymes, including those that convert pyruvate and fatty acids to acetyl CoA and those that oxidize this acetyl CoA to CO2through the citric acid cycle.

Detailed explanation-2: -The process is called oxidative phosphorylation and it happens inside mitochondria. In the matrix of mitochondria the reactions known as the citric acid or Krebs cycle produce a chemical called NADH. NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP).

Detailed explanation-3: -Most cellular activities take place within the cytoplasm, such as many metabolic pathways including glycolysis, and processes such as cell division. The concentrated inner area is called the endoplasm and the outer layer is called the cell cortex or the ectoplasm.

Detailed explanation-4: -The chemical reactions takes place in mitochondria is Oxidative phosphorylation and it happens inside the mitochondria. It is a process of conversion of oxygen to water. It comprises an enzymatic series of electron donor and acceptors which releases energy.

Detailed explanation-5: -The functions of mitochondria obviously include oxidative phosphorylation to produce cellular ATP, but they also have important roles in ion homeostasis, in several metabolic pathways, in apoptosis and programmed cell death, and in ROS production and consumption.
