Question
If the NADP+/NADPH ratio increases then this would probably lead to: A. Increased activity of the pentose phosphate pathway B. Increased production of NADPH C. Decreased activity of the pentose phosphate pathway D. Increased production of NADP+
Solution
The NADP+/NADPH ratio is a measure of the cell's redox state. If this ratio increases, it means there is more NADP+ relative to NADPH. NADP+ is the oxidized form and NADPH is the reduced form.
The pentose phosphate pathway is one of the main ways that cells produce NADPH. Therefore, if the NADP+/NADPH ratio increases, it suggests that there is a need for more NADPH. This would likely lead to an increased activity of the pentose phosphate pathway to produce more NADPH and restore the balance.
So, the answer is A. Increased activity of the pentose phosphate pathway.
