Question

Lucille is finding it difficult to play soccer after school. Her doctor thinks that her cells might not be getting enough oxygen. When Lucille talked about it with a friend, her friend said there might be a problem with Lucille’s respiratory system or circulatory system. What do Lucille’s cells need in order for her body to function properly? How might a problem with Lucille’s respiratory system or circulatory system make it difficult for Lucille to play soccer?
Ezra eats a cheese sandwich for lunch. Cheese contains a lot of protein, and bread is mostly starch. Ezra plans to play basketball later in the afternoon. He is breathing normally.




What does Ezra need from the food he ate and the air he breathes so that he can play basketball? How do Ezra’s body systems work together to get the molecules he needs into his cells? How do his cells use these molecules to release energy for his body to run?

Answer 1

Explanation:

Lucile

Lucile cells needs a huge abundance of glucose and oxygen supply in order for her body to function properly and participate in a soccer game.

Playing a soccer game is energy demanding. The body's energy supply is met by the metabolism of glucose in cells using oxygen.

The problem with Lucille's respiratory and circulatory system can make it difficult for her to take part in soccer game because the needed energy would not be available for her to participate in the game.

• Respiratory system is saddled with the responsibility of bringing enough oxygen to body system through gaseous exchange and metabolism.
• The circulatory system carries the oxygen to the different body cells to where they are need. It also takes the deoxygenated blood to where they can get oxygenated.
• We can clearly see that if respiratory and circulatory systems are not functioning well, Lucille's cells will not be able to furnish her with the much needed energy.

Ezra

Ezra needs energy to play basketball well. The energy is produced via the glucose in the starch and the oxygen from breathing.

When starch is broken down, glucose is produced.

How it works;

The digestive, circulatory and respiratory systems are all important here. They ensure that Ezra gets the needed energy from the food he is eating. Proteins also have the capability of producing energy when there is shortage of starch in the body.

Ezra's digestive system through a couple of processes releases glucose from the food he eats especially the bread in the sandwich.

The glucose is stored in the body and made available for use when in need.

The glucose is used to produce energy.

When Ezra breathes, the circulatory system ensures gaseous exchange with the surroundings. Oxygen rich blood is taken the cells where they combine with glucose for their metabolic actions. Oxygen deficient bloods are carried away.

In the cell, a special apparatus called the mitochondria combines glucose with oxygen and energy is liberated. The energy is used by Ezra to run while playing basketball
