• Their cells don’t have enough glucose or oxygen.

• Their cells don’t have enough carbon dioxide.

• Their cells are too small.

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.
