Explain how carbohydrates and lipids are similar/different.

Carbohydrates and lipids are similar in that they are both sources of energy but they are different in the amount of energy they produce.

Explanation:

Carbohydrate and lipids are similar in the sense that both of them are  parts of foods consumed by humans and the two marcro molecules are good sources of energy for the body cells. The carbohydrate has to be broken down to glucose before it can be absorbed by the body cells. This is because glucose is the only energy source that the body cells can use. The lipid has to be converted to glucose through biochemical reactions such as gluconeogenesis before the cells can use it.

The basic difference between the two energy sources is that the amount of energy that they supply is quite different. Lipid contains more energy than carbohydrate; carbohydrate can only supply about one-quarter of the energy that lipid can supply.
