Answer:
That would be A. Covalent bond!
Explanation:
Since the bond formed is an ester bond, these bonds are covalent in nature and so the answer is A.!
Answer:
enzymes are organic catalyst, the speed up the rate of biochemical processes
Explanation:
enzymes are protein in nature
enzymes are not consumed during the biochemical reaction
enzymes are specific in action
they require optimal temperature for their action.
Answer:
It decreases the levels of cAMP in the cell, repressing transcription from the lac operon.
Explanation:
When glucose is absent, cAMP serves as coactivator binds to CRP, the catabolite gene activator protein. The CRP-cAMP complex binds to the site near the lac promoter and stimulates the expression of the operon by RNA polymerase many folds.
Catabolite repression refers to inhibition of the synthesis of enzymes of lactose catabolism when glucose is present as an energy source. In the presence of glucose, synthesis of cAMP is inhibited resulting in its lower cellular concentration. The lower cAMP levels do not allow the binding of cAMP and CRP. The result is reduced expressed of lac operon.
Answer:
Chlorophyll is a green pigment which is present inside the chloroplast. Chlorophyll is responsible for the conversion of sun energy into chemical energy in the process of photosynthesis. Photosynthesis is a process in which energy is produced by the combination of carbondioxide and water in the presence of sunlight produces glucose and oxygen. This sunlight is absorbed by chlorophyll which is present in the leaves.
