carbohydrates
adenosine triphosphate
Carbohydrates, as a class, provide the most readily available energy source for cells. The complex carbohydrates will split to simple sugars for immediate fuel.
Proteins
GLycogen is basically just long strings of glucose molecules hooked together. They are found in muscles and the liver, and provide an energy source when glucose is not readily available in the bloodstream.
carbohydrates
adenosine triphosphate
Glucose is the energy that is locked inside an organic molecule most readily accessible in.
lIPIDS
Energy rich molecules are mainly carbohydrates as well as lipids and proteins.
False. Glucose is not used as an energy source when proteins and fats are not available.
PUMPS (proteins) pump molecules in and out of the cell by using energy
proteins
Carbohydrates, as a class, provide the most readily available energy source for cells. The complex carbohydrates will split to simple sugars for immediate fuel.
Proteins
In one method, transport proteins in the cell membrane "pick up" molecules outside the cell and carry them in, using energy. Transport proteins also carry molecules out of cells in a similar way.
Lipids do not dissolve as easily as carbohydrates and proteins. Carbohydrates and proteins are readily absorbed by the digestive system and provide the top sources of energy. The lipids tend to clog up the blood and should be avoided.
