Which of these digestive enzymes is not produced by the pancreas?
pancreatic amylase |
|
trypsin |
|
lipase |
|
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.
Which of the following represents the largest value?
1 mL |
|
1 ML |
|
1 cL |
|
1 kL |
Mega (M) is 106, kilo (k) is 103, centi (c) is 10-2, milli (m) is 10-3 so 1 ML represents the largest value.
Which of these parts of digestion takes place in the mouth?
breaking down fats |
|
absorbing nutrients |
|
breaking down starches |

breaking down proteins |
Digestion begins in the mouth where the teeth and tongue break down food mechanically through chewing and saliva, via the enzyme salivary amylase, starts to break starches down chemically. From the mouth, food travels down the esophagus where contractions push the food into the stomach.

side effects |
|
