Metabolism Chapter 2

Diana has a digestive disorder that doesn’t allow her to break down the starch in her digestive system. Could this affect her energy levels if she went for a run?

• Yes, because it would limit the amount of oxygen in her cells.

• No, because she would have enough amino acids in her cells.

• No, because she would still have oxygen in her cells.

• Yes, because she would not have enough glucose in her cells.

Teddy is tired and lacks energy. What body system(s) should the doctor check to find out if Teddy has enough glucose?

• Digestive and circulatory system

• Respiratory and circulatory system.

• Oxygen

• Glucose and oxygen

Patrick eats lots of candy which has a high glucose (sugar) content. How will this affect his digestive system?

• His digestive system won’t have to work as hard because glucose doesn’t need to be broken down and can be absorbed easily.

• His digestive system will have to combine the glucose into starch so that his body can absorb it.

• His digestive system will have to combine proteins to make amino acids.

What is the best way to describe your Metabolism?

• It's how your body Breaks down food for energy

• It's how you body takes in Oxygen to the Cell

• It's how your body process molecules from air and food to give your energy.

• It the process of breaking down molecues so they can fit in your body's Cells

Why would it be a problem for your cells to make energy if your digestive system isn't working properly?

• Cells need to breathe

• The molecules will not be broken down small enough to enter cells

• The amino acids would get lost

• There would be oxygen loss
