Energy Carriers in Respiration (Leaving Cert Biology): Quizzes

ATP and NADH

Primary energy carrier

Three phosphate groups

Adenine, ribose, 3 phosphates

Between last two phosphate groups

$\text{ATP} \rightarrow \text{ADP} + \text{P} + \text{Energy}$

$\text{ADP} + \text{P} + \text{Energy} \rightarrow \text{ATP}$

High-energy electron carrier

Electrons and hydrogen ions

2 electrons and 1 $\text{H}^+$ ion

$\text{NAD}^+ + 2e^- + \text{H}^+ \rightarrow \text{NADH}$

High energy electrons and $\text{H}^+$ ion
