What organelle is responsible for energy production?
A
nucleus
B
mitochondria
C
ribosome
D
cell membrane
Explanation: 

Detailed explanation-1: -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-2: -Mitochondria interact with the endoplasmic reticulum, lysosomes, cytoskeleton, peroxisomes, and nucleus in several ways, ranging from signal transduction, vesicle transport, and membrane contact sites, to regulate energy metabolism, biosynthetic processes, apoptosis, and cell turnover.

Detailed explanation-3: -Mitochondria is responsible for the production of energy in the cell. Mitochondria is also known as the powerhouse of the cell. It has a double membrane-bound structure. They are found inside the cytoplasm of the cell and synthesize energy in the form of ATP molecules.

Detailed explanation-4: -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-5: -Energy production mostly takes place on the folds or cristae of the inner membrane. Mitochondria convert chemical energy from the food we eat into an energy form that the cell can use. This process is called oxidative phosphorylation. The Krebs cycle produces a chemical called NADH.
