Selected Answer: Skeletal system Answers: Circulatory system Muscular system Skeletal system Nervous system Response Feedback: The skeletal system protects organs, gives the body support and allows it to move, and also plays a role in the formation of blood cells. The circulatory system distributes oxygen, nutrients, water, hormones, and other electrolytes; it also has a role in fluid and electrolyte balance. The muscular system allows the body to move and produces heat. The nervous system regulates and coordinates other systems, and also has a role in sensation and memory. Question 14 16.6 out of 16.6 points Match each term to its definition.

Question 2 2.3 out of 2.3 points How do cells obtain energy? Selected Answer: Cells break bonds in ATP molecules. Answers: Energy is made in the liver and released into the blood for the cells to use. Cells break down protein molecules. Energy stored as fat is released into the blood. Cells break bonds in ATP molecules. Response Feedback: Cells obtain energy by breaking phosphate bonds in the ATP molecule. The liver does not release energy into the bloodstream; cells release energy when they need it. Proteins, fats, and carbohydrates can all be used for energy production; however, those substances must first be converted to ATP.
