10. We use ……………… energy when we sleep.​

Answer 1

We use more energy when we run than when we walk.

We use less energy when we sleep.

Answer 2

1. The reason you use energy when walking or jogging on the flat is not that you are moving your entire body a given distance. It is that you are moving your limbs up and down many times, each movement resulting from muscular contractions that convert stored energy partly into movement and partly into heat.

2. Despite the fact that you are resting, your body still consumes energy when you sleep. Energy use is particularly high during REM (rapid eye movement) sleep. During this time, your brain is highly active and you burn the most glucose, your body's source of fuel.
