BIOLOGY HELP!!!!!

1. The correct answer is pH.

The activity of the enzymes might be affected by environmental changes such as change in pH. Each enzyme has the point when it is the most active and this value is known as the optimum pH. Extremely high or low pH values can lead to loss of enzyme activity and stability.

Phosphofructokinase is sensitive to acidity, meaning that it is inhibited by low pH levels.

2. The correct answer is temperature.

Enzyme is sensitive to the environmental conditions such as temperature changes.

Temperature is a factor that usually increases the rate of enzyme-catalyzed reactions by increasing the activity of enzymes. But, after reaching the optimum temperature, reaction rate abruptly declines. This happens because enzymes are deactivated or denatured at a certain temperature (above 40° C).

Mo says it was the environment that made them who they are; Jasper says it was because of genetics. Which is it? Construct an ex
bija089 [108]

Answer:

It's the nature vs nurture situation. While the genetics of a person does control the physical traits he/she may develop, the environment also has a major role to play here. For instance, the person may have the genes for developing a tall height. If, however, that person is not provided with the right kind of nutrition and the right time, it is very likely that he/she will not grow as tall as they had the potential for. Similar explanation for non-physical traits.

This is not an 'either/or' type of argument. Genetics and the environment have a collective impact in shaping the person into who they are and while the balance may shift to one side or the other in certain cases, it does not cancel out or negate the other's effect.

Hope that answers the question, have a great day!
