Well, your body always has some kind of energy. If you eat, then it can use the food for energy for quite a while. If that runs out because you haven't eaten for a long time, then your body will start using fat for energy. If that runs out, then it will start using muscle (which is very bad, since your heart is a muscle). If you are very low on immediately available energy, your body will react by making you feel tired, so that it has time to convert more energy while your body sleeps.
What else can I help you with?
Why do skeletal muscles need large amounts of ATP?
ATP stands for adenosine triphosphate. It is needed to make muscles move. It is created by cellular respiration which creates energy for cells to function. Then those properly energized and properly functioning cells make our muscles move when told to do so by our brain.
What is the function of the animal cell mitochondria?
It has a universal function. That is to produce energy
Does exercise produce energy in muscles?
yes it can and if you have a healthy diet and do lots of exercise you will have lots of oxygen to produce energy in muscles and when you exercise your heart beats and that means energy is going through your muscles hope this helped.
How do muscles produce energy?
muscles use chemical energy in glucose , as the bonds in glucose break, chemical energy changes to mechanical energy and the muscle contracts.. well there you go that how you produce mechanical energy :)
When do muscles energy do work?
When any function has to be performed by body , muscles use energy. It helps in doing work.
What do muscles need to produce energy for movement?
the nervous system
Importance of energy to the body?
energy in your body sends signals from your brain to your muscles to function
Why do we need oxygen in our blood for our bodies to function properly?
Oxygen is essential for our bodies to function properly because it is needed for the process of cellular respiration, which is how our cells produce energy. Without enough oxygen in our blood, our cells would not be able to generate the energy needed for basic functions like breathing, moving, and thinking.
Where do you get your energy from?
We get our energy from the food we eat, which is converted into fuel for our bodies to function properly.
Why do muscles have more mitochondria compared to other cell types?
Muscles have more mitochondria compared to other cell types because they require a lot of energy to function properly. Mitochondria are the powerhouses of the cell, producing energy in the form of ATP through cellular respiration. Since muscles need a high amount of energy for contraction and movement, they have more mitochondria to meet this demand.
What two substances does the brain require to function properly?
The brain requires oxygen and glucose to function properly. Oxygen is needed for metabolism and energy production, while glucose is the main source of energy for brain function.
Identify three chemicals that the body needs for muscles to work properly?
Three chemicals that the body needs for muscles to work properly are calcium, potassium, and magnesium. Calcium is required for muscle contraction and relaxation, potassium helps in nerve signaling to muscles, and magnesium is essential for energy production and muscle function.
