Metabolism & Nutrition, part 2: Crash Course A&P

The video explores how the body processes food, focusing on metabolism and energy conversion. It explains the law of conservation of energy, cellular respiration, and the roles of insulin and lipoproteins. The video also covers nutritional states, glucose management, and the impact of diabetes on metabolism. It emphasizes the importance of understanding these processes for maintaining health.

What happens to amino acids from bacon during digestion?

• They are converted into molecules that can be broken down for energy.

• They are excreted as waste.

• They are stored as glycogen.

• They are directly oxidized into energy.

What does the law of conservation of energy state?

• Energy can be created and destroyed.

• Energy is only used during exercise.

• Energy can only change forms.

• Energy is always stored as fat.

What is the primary source of immediate fuel for neurons?

• Fats

• Proteins

• Glucose

• Vitamins

What happens during the post-absorptive state?

• The body converts proteins into glucose.

• The body increases blood sugar levels.

• The body uses stored supplies for energy.

• The body stores excess glucose as fat.

How does insulin affect blood sugar levels?

• It increases blood sugar levels.

• It decreases blood sugar levels by storing glucose.

• It has no effect on blood sugar levels.

• It converts glucose into proteins.

What is the role of lipoproteins in the bloodstream?

• They store glucose.

• They transport lipids as an emulsion.

• They break down proteins.

• They convert fats into amino acids.

What is the function of HDL cholesterol in the body?

• It delivers glucose to fat deposits.

• It gathers cholesterol from the blood and artery walls.

• It breaks down triglycerides.

• It increases blood sugar levels.

What hormone is released when blood sugar levels decrease?

• Adrenaline

• Insulin

• Glucagon

• Cortisol

What process does the body use to produce glucose from non-carbohydrate sources?

• Lipogenesis

• Gluconeogenesis

• Glycogenesis

• Glycolysis

Why might sudden weight loss be an early sign of diabetes?

• Because glucose is being stored excessively.

• Because glucose is being excreted instead of stored.

• Because the body is producing too much glucagon.

• Because insulin levels are too high.
