Yes or no

is oxygen used in anaerobic respiration reactions?

is oxygen used directly during aerobic reactions?

do all living things utilize oxygen during respiration reactions?

1. No.

2. Yes

3. No

Explanation:

Requirement 1.

At the time of the cellular respiration process, some living systems use an organic molecule as the terminal electron acceptor. Procedures which is used by an organic unit to regenerate NAD+ from NADH are collectively referred to as fermentation. In opposition, some living systems use a chemical molecule as a terminal electron acceptor. Both of these methods are called anaerobic cellular respiration. In anaerobic cellular respiration process, organisms convert the energy for their use in the absence of oxygen. From this, we can understand that the organisms do not use oxygen in anaerobic respiration reactions.

Requirement 2

At the time of aerobic cellular respiration, glucose reacts with oxygen. From this reaction, ATP is produced. This produced ATP is directly used by the cell. During this reaction, carbon dioxide and water are produced as a byproduct. The overall equation for aerobic cellular respiration is:

C6H12O6 + 6O2 = 6CO2 + 6H2O + ATP

There are three stages of aerobic reactions:  glycolysis, the Krebs cycle, and oxidative phosphorylation. Among this three reactions, glycolysis is an anaerobic process.

Requirement 3

We know that there are two types of the cell respiration process. One is aerobic and another in anaerobic respiration. Some prokaryotes, some species of archaea and bacteria, use anaerobic cellular respiration. They are also living things, but they don't use oxygen during the respiration process. So, we can say all living things don't utilize oxygen during the respiration process.

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther
