As part of digestion, the liver produces bile which breaks down:
fat |
|
protein |
|
sugars |
|
starches |
The liver produces bile which emulsifies (separates) fat.
Which of these digestive enzymes is not produced by the pancreas?
trypsin |
|
lipase |
|
pancreatic amylase |
|
gastric acid |
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 large intestine does which of the following?
breaks down fats |
|
processes the physical waste produced by digestion |
|
breaks down proteins |
|
breaks down starches |
The large intestine (colon) follows the small intestine and processes the physical waste produced by digestion, absorbing water and minerials that remain back into the body. Solid waste is then stored in the rectum while liquid waste is stored in the bladder.
In cell biology, where does DNA replication take place?
Golgi apparatus |
|

|
cytoplasm |
|
mitochondria |
The cell nucleus contains the genetic material of the cell and is where DNA replication takes place.
