Question

How many times must the Calvin cycle turn for the plant cell to be able to produce one molecule of glucose?

A) one
B) two
C) three
D) six

Answer 1

Answer;

D) six

Explanation;

• The Calvin cycle is the cycle of chemical reactions performed by plants to FIX carbon from CO2 into three-carbon sugars.
• The three-carbon sugars may be in turn used to make amino acids, nucleotides, and more complex sugars such as starches. The sugars created in the Calvin cycle are used by plants for long-term energy storage, unlike ATP which is used up quickly after it is created.
• The main function of the Calvin cycle is to create three-carbon sugars, which is used to build other sugars such as glucose, starch, and cellulose.

Answer 2

The answer is - Six

A total of 6 turns of the Calvin cycle are needed to make one glucose molecule. Two molecules of G3P are needed to produce one molecule of glucose.

The Calvin cycle is a light independent process and a series of chemical reactions occur in it. These reactions take place in chloroplasts during photosynthesis.
