Answer:
a. In chlorophyll photosystems, the photons excite electrons that are transferred from donor to acceptor molecules in a process that involves oxidation-reduction reactions
b. As negative controls could be produced targeted mutations in genes encoding for enzymes that are not involved in the growth and in the photosynthetic activity
c. The plants that have many classes of photosynthetic pigments absorb light in different ranges of the visible spectrum, thereby it may confer an adaptive advantage to these plants
DNA contains the genetics . DNA tells the cells how to function
The answer to number 4 is D
The correct answer is A! Hope this helped!
Answer:
D) lowering the energy for activation.
Explanation:
Just like chemical catalysts that accelerate the rate of chemical reactions, enzymes are biological catalysts that accelerate the rate of biochemical reactions.
Majorly, a catalyst works by lowering the activation energy required for a specific reaction. The lower the activation energy for a reaction, the faster the rate of that particular reaction.
Hence, an enzyme accelerates the rate of reaction by lowering activation energy of the reaction.
