Question

Mitochondria takes in nutrients, breaks it down, and creates energy for the cell. The process of creating cell energy is known as cellular respiration. Most of the chemical reactions involved in cellular respiration happen in the mitochondria.

Answer 1

Mitochondria are cellular organelles responsible for ATP production through cellular respiration, a multi-stage process that converts nutrients like glucose into energy, requiring oxygen and producing carbon dioxide.

Step-by-step explanation:

Understanding Mitochondria and Cellular Respiration

Mitochondria are known as the "powerhouses" or "energy factories" of a cell, crucial for the production of adenosine triphosphate (ATP), the main energy-carrying molecule within the cell. The process of ATP production is called cellular respiration, which involves the breakdown of glucose and other nutrients. This happens through several stages:

• Glycolysis occurs in the cytoplasm, where glucose is split to form pyruvate.
• The pyruvate is transported into the mitochondria, where it enters the Krebs cycle.
• The energy from the Krebs cycle is transferred to an electron transport chain, where ATP is produced in large amounts.

This entire process requires oxygen and produces carbon dioxide as a waste product, which is exhaled. The number of mitochondria within a cell correlates with the cell's energy demands

Answer 2

Mitochondria are organelles that produce ATP, the cell's main energy-carrying molecule, through cellular respiration. This process occurs in the mitochondria and requires oxygen while producing carbon dioxide as a waste product.

Step-by-step explanation:

Mitochondria (singular = mitochondrion) are organelles in a cell that are responsible for making adenosine triphosphate (ATP), which is the cell's main energy-carrying molecule.

Cellular respiration is the process through which ATP is produced using the chemical energy from glucose and other nutrients. This process primarily occurs in the mitochondria and requires oxygen while producing carbon dioxide as a waste product. The carbon dioxide we exhale comes from the cellular reactions within mitochondria.
