Biological Oxidation and Enzymes Quiz

Biochemistry is defined as:

• The study of chemical reactions in food preparation

• The science of life at the molecular level

• Study of food preservation

• Analysis of soil and minerals

Biochemistry is related to nutrition because it:

• Studies flavors in food

• Explains nutrient functions and metabolism

• Focuses only on protein structure

• Deals only with digestion

Biological oxidation refers to:

• Burning of fats in the kitchen

• Energy production through oxidation in living cells

• Cooking food in oxygen

• Color change in cut fruits

The major site of biological oxidation in cells is:

• Nucleus

• Golgi body

• Mitochondria

• Ribosome

Which of the following is a product of biological oxidation?

• Oxygen

• Glucose

• ATP

• RNA

The final electron acceptor in the electron transport chain is:

• Glucose

• NADH

• Oxygen

• Carbon dioxide

The main function of the Electron Transport Chain is to:

• Store glucose

• Generate oxygen

• Synthesize ATP

• Digest fats

Oxidative phosphorylation occurs in the:

• Cytoplasm

• Nucleus

• Mitochondrial inner membrane

• Endoplasmic reticulum

The energy released from electron transfer in ETC is used to:

• Break proteins

• Pump protons across the mitochondrial membrane

• Activate ribosomes

• Synthesize glucose

ATP synthase is involved in:

• Glucose digestion

• Proton transport

• Synthesis of ATP from ADP

• DNA replication
