As well as allowing the mothers to take care of their offspring in a safe and nurturing condition. Therefore the hikers passing by the pens most likely would see Pregnant females and young caribou within the pens.
Considering the choices;
A. blood glucose level and pH
B. amount of light and temperature
C. amount of light and pressure
D.
temperature and pH
Answer;
D.
temperature and pH
The two factors affect an enzyme's operation the most is the temperature and pH.
Explanation;
Enzymes work best at optimum pH and temperature.
At low temperature for example the enzymes are inactivated while at high temperatures enzymes are denatured.
At optimal temperature and pH; the chemical reaction rate is optimal.
Correct answer: A). The enzyme influences the speed of change from substrate to product
The enzymes are the biological catalyst that speed up the rate of chemical reactions by decreasing the activation energy of the reaction pathway.
They increase the speed of change of substrate to the product and it remains unchanged in the reaction. Hence, it can be used again and again.
Enzymes are highly specific in nature, only a specific substrate binds to the enzyme's active site. Hence, a particular enzyme is required to catalyze a reaction.
The answer is to this question is A
