In a second experiment, variety A seedlings at both temperatures were treated with a chemical that prevents NADH from being oxidized to NAD .Predictthe most likely effect of the chemical on metabolism and oxygen consumption of the treated seedlings. Explainyour prediction.

No metabolism occur and decrease oxygen consumption.

Explanation:

There is adverse effect of chemical on metabolism and oxygen consumption of the treated seedlings because NADH is very important because it maintains the hydrogen pumping that produces ATP molecules. If NADH is oxidized to NAD, then the metabolism did not occur in the seedlings and due to no metabolism, oxygen consumption is also greatly affected.
