Question

The energy stored in ATP in the bond. Which describes a carbolic reaction? a. It consumes energy b. It builds up large molecules c. It goes "uphill" energy wise d. It includes photosynthesis e. It includes cellular respiration The figure above illustrates a process in which amino acid isoleucine can inhibit its own production through a process known as a: a. competitive inhibition b. feedback inhibition c. non-specific inhibition d. specific inhibition. e. feedback induction Planting trees is a possible way to decrease global warming Which mechanism supports this use for trees a. Trees provide shade that cools the planet b. Trees collect the energy of photons that c. Trees create O_2 which reflect sunlight can't heat the planet from the planet d. Trees regulate humidity in the atmosphere e Trees remove CO_2 from the atmosphere

Explanation / Answer

12. The energy............ bond

e) E

ATP contains high energy phosphate bonds. The bond is called as phosphoanhydrite bond. A large amount of energy is required for the synthesis of this bond. So, when this bond is broken, a large amount of energy is released, which in turn is used by the cell for it's metabolic activities.

13. Which ............reaction?

e) It includes cellular respiration

During Catabolic reactions, complex molecules are broken down into smaller and simpler molecules. These reaction result into release of energy. During cellular respiration, larger molecules like carbohydrates are broken into carbon dioxide and water along with generation of energy (which is stored in the form of ATP).

14. The figure................as a

b. Feedback inhibition

In feed back inhibition the product (isoleucine in this case) inhibits the activity of enzyme responsible for it's synthesis. The product tends to bind to the allosteric site of the enzyme resulting in alteration of the enzyme corformation, such that it is no longer able to bind with the substrate. (In competitive inhibition, the inhibitor competes with the substrate for binding with the active site)

15. Planting............trees?

c) Trees remove CO2 from the atmosphere

CO2 is a green house gas. It traps heat radiations within the earth's atmosphere. Excessive amounts of CO2 in the atmosphere will result in excessive heating of the earth resulting in global warming. However, plants can absorb CO2 during photosynthesis and hence keep it's concentration under control. Planting of trees will result into more trapping of CO2 and hence will be helpful in reducing the global warming.
