In the lab, you isolate a chlorella mutant that is unable to switch xanthophyll pigments into the inactive, non-heat-dissipating
REY [17]

Answer:

No, because xanthophyll dissipates absorbed light as heat, and in low light environments, such dissipation would decrease photosynthesis and therefore growth.

Explanation:

Xanthophyll is one of the accessory pigments present in organisms. Being an accessory pigment, the function of xanthophyll is to dissipate the absorbed visible light. Since it dissipates the visible light, the light cannot be used by Chlorella to drive the light-dependent reactions of photosynthesis.

When a mutant Chlorella is grown in the shady region, the dissipation of light by xanthophyll would further reduce the rate of photosynthesis. This mutation is not an adaptive feature in shady regions where the rate of photosynthesis is already lower due to limited availability of light and therefore, would not be favored by natural selection and would not spread to the future generations.

Which of the following best describes what happens to an enzyme after it catalyzes a chemical reaction?
Pachacha [2.7K]

Answer:

<em>The correct option is B. It is unchanged and can be used for the same chemical reaction.</em>

Explanation:

Enzymes can be described as proteins which act as biological catalysts. Enzymes can speed up a reaction. During this process, the enzyme itself doesn't get consumed and hence, it can be reused. Enzymes are specific for a particular type of substrate and hence, they can catalyze only those reactions for which they are specific. Hence, option B is correct.

Other options like option A is not correct because the mass of an enzyme will not change after a reaction.
