What is the optimum temperature for the production of glucose in plants

Optimum temperature for the glucose production ( photosynthesis) is  between 50 and 68 degrees Fahrenheit, or 10 and 20 degrees Celsius.

There are two types of reactions during photosynthesis:

Light dependent reactions of photosynthesis are not affected by changes in temperature, but the light independent reactions of photosynthesis are dependent on temperature.

These reactions are catalyzed by enzymes. As the enzymes get their optimum temperatures the overall rate increases.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
