Enzymes are biological catalysts. Catalysts work by lowering the amount of energy required to set off a chemical reaction.
Where are the answer choices?
No they don’t, but to be able to have cellular respiration it can perform aerobic cellular respiration. These cells will move electrons back and forth across their cell membrane. Other types of prokaryotes cannot use oxygen to perform cellular respiration, so they perform anaerobic respiration.
I believe the answer is proteins. hope this helped! :)
