<span>Certainly. Every organism has a variety of different characteristics. One person writing a key might choose to use different characteristics than another person would use.
For example: Here's a key for separating fish, snake, frog and mouse
1.
A. Has scales on its skin ... 2
B. Has no scales on its skin ... 3
2.
A. Breathes with gills - fish
B. Breathes with lungs - snake
3.
A. Has hair or fur - mouse
B. Has no hair or fur - frog
Here's a different key for the same four animals:
1.
A. Has four legs ... 2
B. Does not have 4 legs ... 3
2.
A. is warm-blooded - mouse
B. is cold-blooded - frog
3.
A. has fins - fish
B. has no fins - snake</span>
The true statements are:
- Substrate level phosphorylation ocvurs during Pyruvate oxidation
- 32 ATP molecules can be made by cellular respiration but only 2 ATP molecules when oxygen is lacking
- Electrons move from protein to protein due to increasing electronegativity in the electron transport chain
- ADP is phosphorylated in the matrix of the mitochondria during oxidative phosphorylation
- ATP inhibits pyruvate dehydrogenase by feedback inhibition
<h3>What is glucose oxidation?</h3>
Glucose oxidation refers to the process in the cells in which glucose molecules are oxidized to form ATP and carbon dioxide in the presence of oxygen.
The first stage of glucose oxidation is the conversion to pyruvate.
Pyruvate is oxidized to acetylCoA.
AcetylCoA enters the citric acid cycle to produce reducing equivalents, NADH for the electron transport chain.
- The true statements about pyruvate oxidation is that there is substrate level phosphorylation during the process
- When there is sufficient oxygen, 36 ATP molecules can be made (theoretically) by cellular respiration. However, when oxygen is lacking, only 2 ATP molecules are made.
- In the electron transport chain of cellular respiration, electrons move from protein to protein due to increasing electronegativity
- During oxidative phosphorylation, ADP is phosphorylated in the matrix of the mitochondria
- Aerobic respiration can be regulated by feedback inhibition of pyruvate dehydrogenase by ATP.

Histone deacetylase is responsible for removing the acetyl group from the histone 3 lysine 9 residue. Remember that deacetylation is one step in converting euchromatin to heterochromatin. Because euchromatin is transcriptionally active (transcriptional machinery is able to reach gene of interest), and blocking histone deacetylase activity would result in an the DNA remaining as euchromatin, we would expect to see an increase in transcriptional activity.
So there’s your answer: An increase in transcriptional activity.
Answer:
A gene is a section of a chromosome that codes for trait.The specific combination of alleles an organism has is called its genotype which affects the organisms features.
