Leni [432]

Answer: Option B

The enzyme has changed shape because of high temperature.

Explanation:

Enzymes are biological catalysts in living organisms that speed up the rate of chemical reactions.

High temperature changes the shape of enzymes.

Increase or high temperature lead to decrease in enzymes activities. This is due to enzyme protein been denatures by high temperature which is the breaking of molecular bonds within the enzyme protein. When the enzymes bonds are broken, the shape of the enzymes changes and they no longer act as catalysts.

The process of phagocytosis involve all of the following except
evablogger [386]

Hello, I figured your question was missing its options so I went online to find them. Here they are:

The process of phagocytosis involves all of the following EXCEPT :

a. adhesion.

b. secretion of cytotoxins.

c. elimination.

d. vesicle fusion.

e. chemotaxis.

Answer:

The correct answer is: b) secretion of cytotoxins.

Explanation:

Phagocytosis is a mechanism performed by cells in which the plasma membrane engulfs a large particle. Phagocytosis is used by cells in the immune system to ingest pathogens like viruses and bacteria.

Phagocytosis consists of many steps:

  1. activation - the phagocytes that were resting are activated in the inflammatory response when a pathogen enters the body.
  2. chemotaxis  - this refers to the process in which the phagocyte moves to the pathogen by following the chemical factors released by these germs.
  3. adhesion - the phagocyte attaches to the pathogen.
  4. ingestion /vesicle fusion - the phagocyte sends pseudopods to engulf the pathogen, and places it in a phagosome, which is an endocytic vesicle. The phagosome and the phagocyte will fuse so the pathogen gets inside.
  5. elimination - the pathogen is destroyed in the phagocyte by the lysosomes present in it.

<u>The</u><u> secretion of cytotoxins</u><u> is not a part of the phagocytosis, and is a process exclusive to </u><u>T cells</u><u> (leukocytes that lack the ability to phagocyte).</u>
