Figure 17-1 The Citric Acid Cycle
Use Figure 17-1 to identify the element marked with a letter. (Example: CO₂, H₂O)
-The ion(s)or molecule(s)labeled G is (are)

Question

Quizplus · Accepted Answer

The molecule labeled G is H⁺, which is a positively charged ion. This ion is involved in the enzymatic reactions of the citric acid cycle, specifically during the conversion of succinate to fumarate by the enzyme succinate dehydrogenase. The H⁺ ion is a substrate in the reaction and is ultimately transferred to an electron carrier molecule to produce ATP during oxidative phosphorylation.
