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:
