It is important because it breaks down the food eaten by the animals into nutrients which are needed for their bodies to function well. Not only it is important to animals but also to humans. <span>Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.</span>
The efficiency of 0.7 means 70% of the total output that will be useful.
So in order to answer this type of question you just need to multiply the amount of energy used(150 unit) with the efficiency(0.7)
The calculation will be: 150 x 0.7 = 105 unit
So the amount of useful energy you will get out of it would be: 105 unit
Answer: Option B) allosteric activation
Energy required by the cell is generated in the form of ATP. ATP is hydrolyzed to power many of the cellular processes, increasing the pool of ADP. As the relative amount of ADP molecules increases, they can bind to glycolytic enzymes, which will lead to the production of more ATP. The best way to describe this mechanism of regulation is allosteric activation
Explanation:
Some enzymes have more than one active site. The other site(s) is called allosteric site.
In this case, ADP released from the glycolytic reactions binds to the allosteric sites of glycolytic enzymes, activating them and causing further breakdown of glucose, hence ATP continues to be generated.
ATP + H2O ---> ADP + Pi + free energy
Venus has a dense atmosphere that traps heat, raising the average surface temperature
Option C.
<h3><u>Explanation:</u></h3>
Venus is the planet in our solar system which is second most closest planet to the Sun. And it's well known for its surface temperature which is often exceeding a temperature of 480°C. Although the planet is lying far enough from sun, much farther than mercury, but the secret behind its highest surface temperature lies in its atmosphere.
Venus has an atmosphere which is 4 times denser than that of earth. And it's atmosphere is composed of 95.6% carbon dioxide. This is well known as a greenhouse gas. The atmosphere in venus is so thick that the surface of venus is never visible from earth. The dense atmosphere also consists of clouds of sulphuric acid and nitric acids.
Answer:
The answer is below
Explanation:
They provide structure and support, facilitate growth through mitosis, allow passive and active transport, produce energy, create metabolic reactions and aid in reproduction.
Hope this helps:)
