Answer:
The correct answer is d. high sugar concentrations stimulate cellular respiration, and alcohol is not a by-product of cellular respiration.
Explanation:
As they added sweet grape juice mixture the amount of sugar increased in the content and it is seen that more than 6 % of sugar decreases the rate of fermentation and alcohol concentration also decreases and a moderate amount of glucose concentration in the anaerobic environment increases the fermentation results in more alcohol production.
High sugar concentration decreases fermentation but increases cellular respiration in the yeast, as a result, it uses more sugar for its growth and produce CO₂ and H₂O so alcohol is not the by-product of cellular respiration. Therefore the correct answer is d. high sugar concentrations stimulate cellular respiration, and alcohol is not a by-product of cellular respiration.
They binds and make enzyme-substrate complex. Their shapes are same so they fit together naturally.
Answer:
Lipids store about 9 kilocalories of energy per gram, almost twice that of carbohydrates, so they are the preferred fuel in the animal body. Glucose has one great advantage, however, it is soluble in water and blood and thus easy to distribute around the body.

Answer:
The correct answer is a an amino group and a carboxyl group.
Explanation:
Alanine and serine are both amino acids.Alanine is a simple amino acids where serine is a hydroxyl amino acids.
When alanine and serine molecules combine to form a single molecule at that time an amino group and the carboxyl group will be joined together to form a ala-ser peptide linkage.
