What's the difference between monosaccharide, disaccharide, and polysaccharide?

What are enzymes and what are they used for?
Enzymes are a special class of proteins that are used as catalysts.
What type of bond links nucleotide bases together?
Describe where the protons, neutrons, and electrons are in an atom?
In an atom, protons and neutrons cluster together at the center, which is called the nucleus. Electrons orbit around the nucleus.
What's the difference between diffusion and osmosis?
Diffusion all molecules can move freely (water level doesn't change) whereas osmosis there is a semipermeable membrane so only some molecules can pass (water level raises on side of higher concentration).
Which are carbohydrates?
PH2, CO2, C6H12O6, C5H10O5
Carbohydrates only have CHO, so C6H12O6, C5H10O5
What type of bond links amino acids together?
Peptide
