Answer:

Size of the band varied

Explanation:

In the given question, the options are not provided but based on the information provided in the question, it can be predicted.

When the DNA was digested by the HindIII, then the length of the digest came about 1000 bp and the undigested DNA was also found 1000 bp.

When both the bands were analysed by Gel electrophoresis then the bands do not run to the same distance therefore this shows that the size of both the bands was not equal and their size varied.

Thus, the size of the band varied is correct.

Match each product of pyruvate metabolism with the condition under which it is produced. Drag each item to the appropriate bin.
bekas [8.4K]

Answer:

Lactate: fermentation in human muscle

Ethanol: fermentation in yeast and bacteria

Acetyl CoA: aerobic oxidation

Explanation:

Lactate is produced in lactic fermentation in human muscle. Lactic fermentation in muscle cells is a process that occurs alternatively, in situations where the body does not perform aerobic respiration. Considered a short-term metabolic device, activated when the body is subjected to intense physical effort under conditions of low muscular oxygenation.

Alcoholic Fermentation, also known as ethanol fermentation, is the anaerobic pathway performed by yeast and some bacteria, in which simple sugars are converted to ethanol and carbon dioxide. Yeasts usually function under aerobic conditions, either in the presence of oxygen, but are also capable of functioning under anaerobic conditions, or in the absence of oxygen. When oxygen is not readily available, fermentation alcoholic beverages occur in the yeast cell cytoplasm.

Acetyl CoA results from aerobic oxidation. This process occurs in mitochondria during cellular respiration, where pyruvate, the product of glycolysis, can be substituted, and often is, by fatty acids. This is because pyruvic acid is used to form a compound called Acetyl Coenzyme A or Acetyl CoA. In this sense, Acetyl CoA can also be produced by the degradation of fatty acids by a reaction called β oxidation.

Why is it essential that the regulatory mechanisms that activate glycogen synthesis also deactivate glycogen phosphorylase?
Marta_Voda [28]

Answer:

There are two pathways occur in the same cellular compartment, and, if both are on at the same time, a futile ATP hydrolysis cycle results. Using the same mechanism to turn them on/off or off/on is highly efficient.

- "Glycogen Phosphorylase" activity can be allosterically controlled ATP and G6P allosteric inhibitors, AMP allosteric activator as well as, controlled through covalent modification, phosphorylation and via hormones.

- Reaction Catalyzed by Glycogen Synthase:

The activity of glycogen synthase is subject to the same type of covalent modification as glycogen phosphorylase, however, the response is opposite. Glycogen Synthase is activated by G6P. It is also controlled via hormones.
