Select true or false for the following statements:

Question

During cellular respiration, first a molecule of glucose must be split to produce two small molecules. This step is called glycolysis.
Cells without mitochondria cannot break down glucose for energy.
During Cellular Respiration energy is kept when glucose, a sugar, is broken down.
Water forms as a waste product during the second stage of cellular respiration.

Answer 1

Here are the answers to your statements:

1. True - During cellular respiration, glucose is indeed split during the process called glycolysis, resulting in two smaller molecules (pyruvate).

2. False - Cells without mitochondria can still break down glucose for energy, primarily through glycolysis, which occurs in the cytoplasm. However, they will rely on anaerobic processes for ATP production.

3. False - Energy is not kept; rather, it's released when glucose is broken down during cellular respiration. This energy is captured and stored in the form of ATP.

4. True - Water is formed as a waste product during the electron transport chain, which is part of the second stage of cellular respiration (oxidative phosphorylation).
