by the removal of an -OH group and a hydrogen atom

how is a polymer formed from multiple monomers?

the C-H bonds found in carbohydrates store energy

why are carbohydrates important molecules for energy storage?

starch; glycogen

plant cells store energy in the form of ________, and animal cells store energy in the form of __________

ribose

which carbohydrate would you find as part of a molecule of RNA?

nucleotides

a molecule of DNA or RNA is a polymer of:

cellulose forms long filaments, and starch is highly branched

what makes cellulose different from starch?

amino acids

what monomers make up a protein?

lipid; fatty acids and glycerol

a triglyceride is a form of _______ composed of ______ _______ _____ __________

starch and glycogen have similar structures

you can use starch or glycogen as an energy source, but not cellulose because:

phosphodiester vs hydrogen bonds

which of the following is NOT a difference between DNA and RNA?

the R group

which part of an amino acid had the greatest influence on the overall structure of a protein?

all the levels of protein structure

a mutation that alters a single amino acid within a protein can alter:

similar function

two different proteins have the same domain in their structure. from this we can infer that they have:

the nonpolar C-H bonds in fatty acids

what aspect of triglyceride structure accounts for their insolubility in water?

the polar head groups of the phospholipids can interact with water; the fatty acid tails of the phospholipids are hydrophobic

the spontaneous formation of a lipid bilayer in an aqueous environments occurs because:
