Energy Carriers in Respiration (Leaving Cert Biology): Flashcards

ATP and NADH

Adenosine Triphosphate

Primary energy carrier

Adenine, Ribose, Three phosphate groups

Three

Bond between last two phosphate groups

$ATP \rightarrow ADP + P + Energy$

$ADP + P + Energy \rightarrow ATP$

Nicotinamide Adenine Dinucleotide

High-energy electron carrier

Electrons and hydrogen ions ($H^+$)

Two electrons ($2e^-$) and one hydrogen ion ($H^+$)

$NAD^+ + 2e^- + H^+ \rightarrow NADH$

High energy electrons and hydrogen ion

$NADH \rightarrow NAD^+ + 2e^- + H^+$
