Answer:
By preventing the binding of substrate to active site
Explanation:
Competitive inhibitors exhibit a type of reversible inhibition. These are the substances that bind to the binding site of the substrate on the enzyme, that is the active site.
One the competitive inhibitor is bound to the active site on the enzyme, the substrate cannot bind to it and there is no enzyme-substrate complex formation. Hence, the competitive inhibitor inhibits/slow down the enzyme catalysis by occupying the active site of the enzyme and thereby not allowing the substrate to bind to the enzyme.
The instructions for making proteins comes originally from chromosomes
The Chloroplast produces Glucose during light independent reactions.
Simple,
you want a valid prediction about the results of her experiment.
B is out of the picture, leaving only A and C.
Since it's asking about a valid prediction of the results of her experiment then the only logical answer is C.
Thus, your answer.
