In the pancreas, lipase converts fat to:
complex carbohydrates |
|
glycerol and fatty acids |
|
amino acids |
|
simple sugars |
The acids produced by the pancreas contain several enzymes that aid in digestion. Lipase converts fat to glycerol and fatty acids. Pancreatic amylase breaks down complex carbohydrates into simple sugars. Trypsin converts polypeptides (the building blocks of protein) into amino acids.
The energy posessed by a thrown baseball is an example of what kind of energy?

Carbohydrates are found in:
food additives |
|
animal sources |
|
sugars and starches |
|
vegetable oils |
Carbohydrates are major sources of energy for the body and are found in sugars (fruit, cane sugar, beets) and starches (bread, rice, potatoes, pasta).
Which of the following members of the food chain are most alike?
scavengers and decomposers |
|
herbivores and autotrophs |
|
primary consumers and omnivores |
|
producers and tertiary consumers |
Like decomposers, scavengers also break down the dead bodies of plants and animals into simple nutrients. The difference is that scavengers operate on much larger refuse and dead animals (carrion). Decomposers then consume the much smaller particles left over by the scavengers.
