Answer:

3. adding phosphate groups to target proteins.

Explanation:

CDKs are the kinases that add the phosphate groups to their target proteins. These proteins are present in an inactive form and are activated only when cyclins bind to them. The complex formed by cyclins and the respective CDKs activates the later. The activated CDKs then phosphorylate the target proteins. Some proteins are activated while the others become inactive upon phosphorylation. This is how CDKs regulate the progress of cells from one stage of the cell cycle to the other.

Which of the following accurately describes the role of energy in cellular respiration?
zmey [24]

Answer:

The correct answer is option energy is a product.

Explanation:

Cellular respiration is a process in which oxidation of food or glucose takes place to produce energy. This process proceeds in four processes: glycolysis, oxidative carboxylation, Krebs cycle and electron transport chain.

All of this process produces energy in the form of ATP or energy equivalents like NADH and FADH₂.  

1. Glycolysis produces- 2 ATP, 2 NADH,  

2. Oxidative carboxylation produces- 2 NADH,  

3. Krebs cycle produces- 2 ATP, 6 NADH AND 2 FADH₂ and  

4. Electron transport chain produces at last- 24 ATP from these reducing equivalents.

Thus, option energy is a product is a correct option.

<em>Mutualism: </em>

The type of interaction in which both the species involved are benefited, it is called mutualism.

<em>Parasitism:</em>

The type of interaction in which one species is benefited, whereas the other is harmed, it is called parasitism.

<em>Commensalism:</em>

The type of interaction in which one species gets benefited without harming or providing benefits to others is called commensalism.

<em>Competition:</em>

The type of interaction in which both species lose is called competition. It is opposite of mutualism.

<u>Symbiotic relationship:</u>

It refers to the type of interaction in which lastly one species gets benefited. The type of interactions such as <em>mutualism, commensalism, and Parasitism </em>are considered as symbiotic relationship.
