Question

The model contains a large number of mitochondria.

Identify the main role of mitochondria in animal cells.

Answer 1

The main role of mitochondria in animal cells is to produce adenosine triphosphate (ATP), which is the primary energy currency of the cell. This process occurs through cellular respiration, where glucose and other nutrients are metabolized in the presence of oxygen to generate ATP. Mitochondria also play important roles in other cellular functions, including regulation of the cell cycle, apoptosis (programmed cell death), and the maintenance of cellular calcium levels. Additionally, they are involved in metabolic pathways, such as the citric acid cycle (Krebs cycle) and fatty acid oxidation.
