Transfer Molecules (LC 2027) (Leaving Cert Biology): Flashcards

Trap, store, and transfer energy

$ext{ATP/ADP}$, $ext{NAD}^+/ ext{NADH}$, $ext{NADP}^+/ ext{NADPH}$

Adenosine diphosphate

Adenine, ribose, two phosphate groups

Adenosine triphosphate

Three

Contains unstable high-energy bonds that store and release energy easily

$ext{ADP} + ext{energy} + ext{phosphate} ightarrow ext{ATP} + ext{water}$

$ext{ATP} + ext{water} ightarrow ext{ADP} + ext{energy} + ext{phosphate}$

Nicotinamide adenine dinucleotide

Coenzyme

$ext{NAD}^+ + 2 ext{ electrons} + ext{H}^+ ightarrow ext{NADH}$

Nicotinamide adenine dinucleotide phosphate

Photosynthesis

$ext{ADP}$ and $ext{NAD}^+$ (converted to $ext{ATP}$ and $ext{NADH}$)
