Which of these digestive enzymes is not produced by the pancreas?
trypsin |
|
pancreatic amylase |
|
gastric acid |
|
lipase |
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.
A subatomic particle found in the nucleus of an atom. It carries a positive electric charge. This desribes which of the following?
electron |
|
atom |
|
proton |
|
neutron |
A proton is a subatomic particle found in the nucleus of an atom. It carries a positive electric charge.
Which of the following is the formula for power?
\(P = w t\) |
|
\(P = {\vec{w} \over t}\) |
|
\(P = {w \over t}\) |
|
\(P = \vec{w}t\) |
Power is the rate at which work is performed or work per unit time: \(P = {w \over t}\) and is measured in watts (W).
When compared to eukaryotic cells, prokaryotic cells are:
less complex |
|
similarly complex |
|
none of these |
|
more complex |
Cells are classified into one of two groups based on whether or not they have a nucleus. Eukaryotic cells have a nucleus, prokaryotic cells do not have a nucleus and therefore have a less complex structure than eukaryotic cells.
Molecules and atoms that are inputs to a chemical reaction are known as which of the following?
products |
|
components |
|
reactants |
|
fuel |
During a chemical reaction molecules and atoms (reactants) are rearranged into new combinations that result in new kinds of atoms or molecules (products).
