Cellular Metabolism Metabolism – all chemical reactions that occur in the body Two types of metabolic reactions Anabolic ,[object Object]

Goal of Cell Respiration-Make ATP

Anabolic Anabolism provides the substances needed for cellular growth and repair ,[object Object],[object Object],[object Object]

Catabolic Catabolism breaks down larger molecules into smaller ones ,[object Object],[object Object],[object Object],[object Object]

Control of Metabolic Reactions Enzymes- all are proteins ,[object Object],[object Object],[object Object],[object Object]

Do not make anything happen that could not happen on its own Enzymes can be reused over and over Same enzymes catalyses the forward and reverse reactions. They are very specific

The Goal is the production of NADH and FADH2 for use in the ETC—they are electron carriers

ETC ,[object Object],[object Object],[object Object],[object Object],[object Object]

Oxygen if the Final Electron Acceptor Why do we Breath??
