Answer:
The activation energy must be reached. The catalyst makes lower energy pathways available.
Explanation:
Answer:
Here, is the question with the explanations to pick from to complete the question
Tropical rainforests have high species richness of trees. Which of the following statements provides the MOST reasonable explanation why animal species richness is also high in tropical rainforests?
Animals are unable to adapt to climate variability in higher latitudes.
Animals have had the same amount of time to evolve in rainforest areas as trees.
Animal diversification rates are higher than those of trees.
Animals have diversified into the vast number of niches provided by tree diversity
The last option is the most reasonable one
Our answer is:
Animals have diversified into the vast number of niches provided by tree
Explanation:
The reason is that a lot of species are highly specialized to occupy a particular niche. Where that favourable niche exists, the population of that species increases as its offspring colonize new areas.
For example, pH can have an effect of the state of ionization of acidic or basic amino acids. Acidic amino acids have carboxyl functional groups in their side chains. Basic amino acids have amine functional groups in their side chains. If the state of ionization of amino acids in a protein is altered then the ionic bonds that help to determine the 3-D shape of the protein can be altered. This can lead to altered protein recognition or an enzyme might become inactive.
Changes in pH may not only affect the shape of an enzyme but it may also change the shape or charge properties of the substrate so that either the substrate connot bind to the active site or it cannot undergo catalysis.
In geneal enzyme have a pH optimum. However the optimum is not the same for each enzyme.
