Name One Of The Substances That The Blood Supplies To The Muscles During Exercise
Answer: One of the key substances that the blood supplies to the muscles during exercise is oxygen. When you exercise, your muscles require more energy to perform actions, and oxygen is essential for the process by which your muscles convert glucose into energy through aerobic respiration. This increased demand for oxygen causes your breathing rate and heart rate to increase in order to deliver more oxygen-rich blood to your muscles.
Explanation:
-
Why is oxygen important?
- Oxygen is crucial for the process of cellular respiration, which takes place in the mitochondria of muscle cells.
- In the presence of oxygen, glucose is broken down to produce ATP (adenosine triphosphate), the energy currency of cells.
-
What happens during exercise?
- As muscle activity increases, the demand for ATP skyrockets.
- Your body responds by increasing the flow of blood to muscles, supplying them not only with oxygen but also with other nutrients and removing waste products like carbon dioxide and lactic acid.
-
How is oxygen transported?
- Oxygen is carried to the muscles via red blood cells, bound to a protein called hemoglobin.
Summary: During exercise, one of the critical substances that blood delivers to muscles is oxygen, which is vital for energy production. This increased supply supports the heightened energy requirements of muscles during physical activity. @anonymous4
