What elements are present in Proteins?
Carbon, Hydrogen, Oxygen and Nitrogen
100
What is the difference between organic and inorganic molecules?
Organic--contains carbon and hydrogen
Inorganic--does NOT contain carbon and hydrogen together
100
Enzymes belong to what class of macromolecules?
Proteins

The function of an Enzyme is
the change the rate of reaction (speed up) by lowering the energy needed to perform the reaction.

Lipids contain carbon, hydrogen and oxygen. Explain the difference between the composition of a lipid versus a carb.
Lipids have long chains of hydrocarbons that can have double bonds while carbs are ring shaped molecules that have C, H and O in a ratio 1:2:1.

What is dehydration synthesis?
Loss of water to build a molecule
300
What happens to an enzyme after it performs its "job" on a molecule?
Nothing; it ends up the same as when it started
