It does so using various types of mechanism, one is by the production of antibodies.

Antibodies are proteins that are produced by the B-cell and are used by the immune system to identify and neutralize pathogens.

These antibodies also activates proteins known as complements which assist in the killing of bacteria, viruses and the infected cells.

Which of the following would affect the function of an enzyme?
Blizzard [7]

TEMPURATURE:

Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working.

pH:

Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity. Extreme pH values can cause enzymes to denature.

DIFFERENT SUBSTRATES:

Increasing substrate concentration also increases the rate of reaction to a certain point. Once all of the enzymes have bound, any substrate increase will have no effect on the rate of reaction, as the available enzymes will be saturated and working at their maximum rate.

I got these explanations from khan academy :)

At first glance, fermentation of pyruvate to lactate appears to be an optional add-on reaction to glycolysis. After all, could c
Serhud [2]

Answer:

No, glycolysis can not be continued without fermentation in the absence of oxygen.

Explanation:

In the absence of oxygen, cells perform fermentation to oxidize NADH into NAD+. NAD+ is required during the conversion of glyceraldehyde 3 phosphate into 1,3 bisphosphoglycerate. Fermentation reduces pyruvate and oxidizes NADH so that the NAD+ supply is continued to ensure continuity of glycolysis.

If fermentation does not occur under anaerobic conditions, cells will accumulate pyruvate and NADH. Glycolysis could not be continued in the absence of NAD+.
