the mitochondrion is host to which portion of cellular respiration? glycolysis alcoholic fermentation lactic acid fermentation t
MA_775_DIABLO [31]

Answer: The correct answer is Kreb cycle.

Cellular respiration is defined as the oxidation of food into CO₂ ( cabon dioxide) and H₂O ( water) in order to produce energy in the form of ATP ( adenosine triphosphate).

It occurs in three stages that is Glycolysis, Kreb cycle, and Electron transport chain.

Kreb cycle occurs in the matrix of the mitochondria. It includes the oxidation of a two carbon compound that is Acetyl- CoA in order to generate a pool of chemical energy in the form of ATP, NADH, FADH₂.

On the contrary, glycolysis and fermentation occur in the cytoplasm.

Thus, mitochondria is host to Kreb Cycle of the cellular respiration.

Enzymes can be denatured unfolded by what environmental factors
erastova [34]

Enzymes can be denatured unfolded by heat or chemicals.

<h3>What are enzymes?</h3>

Enzymes are proteins that are found in living organisms which are able to increase the rate of chemical reaction and remains unchanged at the end of the reaction.

The factors that can denature enzymes include heat and chemicals. This is because:

  • Higher temperatures disrupt the shape of the active site, which will reduce its activity, or prevent it from working. When the enzyme loses its shape, it is said to have been denatured.

  • These environmental factors can alter the pH level of the enzyme.

Therefore, for an enzyme to perform its functions, the external factors that affects it's activities must be normal and favorable.

Some organelles, such as the endoplasmic reticulum and Golgi bodies, have a large and folded structure. What is an advantage of
bekas [8.4K]

Answer:

Explanation:

In endoplasmic reticulum, many folds leads to an increase in surface area for ribosomes to attach which allows for protein synthesis to occur at an efficient rate.

mitochondria has two membrane,

It has an inner membrane which is folded inside the other. The fold create cristae, which is the site for a portion of cellular respiration.

The folds also enables a large surface area that makes chemical process to occur in an efficient way.
