Answer 5

necleotides and _______

Question 6

carbs function

Answer 6

energy, store simple sugars, plant walls

Question 7

lipids function

Answer 7

long term energy, make cell membranes, molecular messanger

Question 8

proteins functions (enzymes, hormones, antibodies, and structural proteins)

Answer 8

enzymes catalyze important chem. reactions in cells, hormones are messengers that switch cells on and off, antibodies fight forgein cells, and structural proteins give cell shape

Question 9

nucleic acid functrions

Answer 9

DNA carries genetic info and codes for building protein. RNA assists in protein building

Question 10

what are R groups

Answer 10

side chains of amino acids

Question 11

what happens in primary level

Answer 11

sequnence in polypeptide chain is determined by DNA and sequence determines the shape/function. peptide bonds hold them together

Question 12

secondary level

Answer 12

small seconds of folding happen in all polypeptides, hydrogen bonds hold structure in place

Question 13

tertiary level

Answer 13

stabilized by interactions in R groups, like clustering of hydrophobic R groups in center of molecule

Question 14

quaternary level

Answer 14

not all protein have this level, more than one peptide chain bonded

Question 15

what is denaturation

Answer 15

unfolding of protein.

Question 16

what are some conditions for denaturation to happen

Answer 16

heat, change in pH, and salinity
