Question

Rosa eats a peanut butter sandwich for lunch. Peanut butter contains a lot of protein, and bread is mostly starch. Rosa plans to go for a run later this afternoon. Rosa is breathing normally. What does she need from the food she ate and the air she breathes so that she can go on her run? How do Rosa’s body systems work together to get the molecules she needs into her cells? How do her cells use these molecules to release energy for her body to run?

Answer 1

Answer:

answer is above......

Answer 2

Function of Rosa's body system

Explanation:

Glucose and Oxygen is needed to run

• Rosa's cells require oxygen from the air and glucose from the starch in her food to run.

Rosa's body system work together to get the molecules she needed into her cells

• Rosa's respiratory system transports oxygen molecules to her cells and is sent to her cells via the circulatory system.
• Her digestive system must break down the starch in her food into glucose, which is then transported to her cells via the circulatory system.
• The respiratory system, circulatory system, and digestive system work together to send molecules to her cells.

Cells use the molecules to release energy for her body to run

• Cells will produce energy as a result of a chemical reaction involving glucose and oxygen. She will have enough energy to run when her cells release energy.
