strojnjashka [21]

Plant cells, but not animal cells

Animal cells, but not plant cells

Both plant cells and animal cells

Neither animal cells nor plant cells

Answer:

Both plant cells and animal cells

Explanation:

The process where the energy locked up in food is extracted take place in both plants and animal cells.This process is called Cellular respiration.It is the process of combining inhaled and diffused oxygen in the blood with assimilated food substances (glucose,amino acids,fatty acids and glycerol) to produce energy.

In both cells it takes place in the the cytoplasm and mitochondrial.

It begins with Glycolysis, followed by Krebs's Cycle..These two steps gives certain of ATPs to these cells

.However,the largest amount of ATPs is synthesized during oxidative phosphorylation  for maximum of energy to be produced.This process involved the chemiosmosis where protons were diffused into the intramembranes by the proton pump (PMF) and diffused back into the matrix of the mitochondria to generate the electrochemical gradients.

The electrochemical gradients generate the energy for enzymes ATPase synthase needed for phosphorylation of ADP with Pi to give ATPs.

The oxygen act act the final electron acceptor.
