IB SEHS: 3.2 Carbohydrate and Fat Metabolism

What is aerobic catabolism?

• A chemical reaction requiring energy to build larger molecules from smaller molecules in the presence of oxygen

• A chemical reaction requiring energy to build larger molecules from smaller molecules in the absence of oxygen

• Chemical reactions that break down complex organic compounds into simpler compounds in the presence of oxygen

• Chemical reactions that break down complex organic compounds into simpler compounds in the absence of oxygen
