Biology
1 answer:
9966 [12]3 years ago
5 0

Answer:

B

Explanation:

Great variations in temperature and pH from the optimum that an enzyme needs can affect its function. pH affects ionization of the functional groups of amino acids. The interaction of charges of these amino groups helps in stabilizing loops such as those of beta sheets and alpha helices and give the protein its an appropriate shape to function.

Temperatures, on the other hand, while it does not change the ionization of the functional side groups of amino acids, it breaks these bonds of the interactions by giving the molecules enough energy to break free from these bonds hence denaturing the protein.

The tissues of the leaf in the middle of the epidermal cells, into which gases diffuse from the stomata, are called mesophyll. The mesophyll can be additionally separated into two layers, the palisade layer, and the springy layer, both of which are stuffed with chloroplasts, the production lines of photosynthesis.
