Answer:
Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.
Explanation:
Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body. Waste products of digestion pass through the large intestine and out of the body as a solid matter called stool.

Answer:
Cellular respiration
Explanation:
The point of cellular respiration is to get energy for the cell. ATP is the "energy currency" of the cell that enables it to function at normal levels. In cellular respiration, a process called <u>glycolysis</u> breaks down glucose to obtain large amounts of ATP.
The sugar maltose would be digested by the enzyme sucrase. True
