Chapter 2-Energy Systems Review

What key message is depicted in this figure?

• Usable energy is released whenever creatine is combined with phosphate to form phosphocreatine.

• The activation energy required to create creatine from phosphocreatine is greater in slow-twitch muscle cells than in fast-twitch muscle cells.

• The presence of an enzyme lowers the activation energy required to produce ATP from phosphocreatine.

• The creatine produced by this reaction helps build muscle mass.
