D a sandwich is digested and converted to carbon dioxide nd water
Atoms overcome the attractive forces between them through vaporization and sublimation. In vaporization, the atoms are from gas to liquid while in sublimation, it is from solid to gas which skips liquid state. Through this, the attractive force of the atoms does not meet in the liquid state because sublimation does not undergo in liquid phase.

Answer:
- <u>Cell has a limited supply of NAD+</u>
Explanation:
Cellular respiration occurs in the cytoplasm, where glucose is broken down for energy processing. Energy is produced by aerobic respiration in the presence of oxygen, whereas anaerobic respiration can be carried out in an oxygen-deprived environment.
Fermentation is one kind of anaerobic respiration- here, the cells use glucose to generate a Net 2 molecules of ATP from the 6carbon sugar. Glucose is first converted to pyruvate, which is oxidized in a complex process. While 4 ATP are produced in fermentation, 2ATP are used in regenerating NAD+ from NADH2.
Two types of fermentation include lactic acid fermentation and alcoholic fermentation. These occur in single-celled, and multicellular microbes.
