Question

Krebs’ cycle takes place in
A.)Cytoplasm
B.)Chloroplast
C.)Nucleus
D.)Mitochondria

Answer 1

Hint: The cycle through which aerobic and the production of molecules are known as Krebs cycle. This type of reaction takes place in the cell organelles to regulate the metabolic functions.

Complete answer:
We need to know that Mitochondria are a cell organelle which is popularly called the powerhouse of the cell. It is responsible for the power needed for triggering biochemical reactions of the cell. These cells are also the causes of the production of molecules that aid in the signaling process between the cells. The cycle in which the power generation is done and the production of molecules are known as Krebs cycle.
They also help in maintaining the all-important calcium levels in the body. It acts as a thermostat producing enough heat in the body so that it can survive. It reduces the body heat if necessary to a certain extent and it also kills certain cells that are not important for the body or harmful for the body.
Krebs cycle happens in the mitochondrial matrix. Listen carefully about the kreb’s cycle steps which are as follows:

1) It is responsible for producing the power required for all the Biochemical reactions.

2) The cells are causes for the production of molecules that are helpful in the signaling process between the cells.

3) The cycle helps in reducing body heat so that body temperature at all times can be maintained at a constant level.

4) It acts as a thermostat increasing or decreasing the heat required by the body depending on the conditions.

5) By receiving information from various parts of the body the brain understands the functioning of the various parts of the human body. Then it responds by suggesting the organs the necessary preventive mechanisms to start to lessen the damage on the parts.

Hence, the correct answer is option (D)

Note: It is important to know about the Mitochondria and its functions and they help us in remembering Kreb’s cycle. It is responsible for producing the power required for all the Biochemical reactions. The cells are causes for the production of molecules that are helpful in the signaling process between the cells.
