Determine whether this statement is true or false.We need oxygen for our cells so they can get energy from glucose in a process called cellular respiration.

The statement is true. Cellular respiration is a biochemical process that occurs in the cells of organisms where glucose (a simple sugar) is used to produce energy in the form of adenosine triphosphate (ATP). This process typically requires oxygen, particularly during aerobic respiration, which is the most efficient pathway for energy production.

Here's a brief overview of the process:

1. Glycolysis: This is the first step where glucose is converted into pyruvate in the cytoplasm, producing a small amount of ATP and NADH.

2. Krebs Cycle (Citric Acid Cycle): If oxygen is present, pyruvate enters the mitochondria, where it is further processed in the Krebs cycle, generating more NADH, FADH2, and a small amount of ATP.

3. Electron Transport Chain: The NADH and FADH2 produced in previous steps are used in the mitochondria to pass through the electron transport chain, where oxygen serves as the final electron acceptor. This process produces the majority of ATP through oxidative phosphorylation.

In summary, oxygen plays a crucial role in cellular respiration, allowing cells to efficiently extract energy from glucose.
