Which reactions require at least some external energy to start?

• endothermic (endergonic) reactions

• exothermic (exergonic) reactions

• reactions occur spontaneously

• those with an enzyme to catalyze them

What do enzymes do?

• Make reactions occur more quickly

• Make reactions require less ATP

• catalyze chemical reactions

• lower the activation energy for a chemical reaction
