Final answer:
Enzymes such as lipase, amylase, pepsin, and trypsin help break down different types of molecules during digestion. Insulin regulates blood sugar levels, and hemoglobin carries oxygen in the blood.
Step-by-step explanation:
Lipase, amylase, pepsin, and trypsin are enzymes that play important roles in digestion. Lipase breaks down lipids, amylase breaks down carbohydrates, pepsin breaks down proteins, and trypsin breaks down proteins as well. These enzymes help to break down food into smaller molecules that can be absorbed by the body.
Insulin is a hormone that regulates blood sugar levels. It helps to control the amount of glucose in the blood, allowing cells to take in glucose and use it as a source of energy.
Hemoglobin is a protein found in red blood cells that carries oxygen from the lungs to the body's tissues. It binds to oxygen in the lungs and releases it in areas of the body where oxygen is needed.
