16
Q

large molecules of amino acids linked end-to-end. builds and maintains cells and tissues

A

protein

17
Q

small molecule of less than 50 amino acids

A

peptide

18
Q

large molecule of greater than 50 amino acids

A

polypeptide

19
Q

3 levels of protein structural organization

A

primary, secondary, and tertiary structure.

20
Q

structure where molecule coils and folds

A

secondary structure

21
Q

structure where molecule twists and is 3D

A

tertiary structure

22
Q

structure where amino acid sequence “laid out”

A

primary structure

23
Q

protein loses tertiary structure and function and cant is renatured. (caused by heat, extreme pH)

A

protein denaturation

24
Q

information/genetics + structural molecules.

A

nucleic acids

25
Q

building block molecules

A

nucleotides

26
Q

5 types of nucleotides

A

adenine, guanine, cytosine, thymine, uracil

27
Q

3 nucleic acids in the body

A

DNA, RNA, ATP

28
Q

a genetic molecule that makes up chromosomes

A

DNA

29
Q

A, G, T, and C are linked end-to-end in ____

A

DNA

30
Q

large structures in nuclei made of DNA/packaged protein and consist of genes

A

chromosomes

31
Q

there are __ chromosomes in humans

A

32
Q

segments of nucleotide sequences that are decoded by enzymes

A

genes

33
Q

A, G, C, and U nucleotides are in ___

A

RNA

34
Q

produced by enzymes that decode genes. they bind to ribosomes to decode sequences into amino acids for new proteins.

A

RNA

35
Q

gene sequence in DNA to RNA molecules to new protein molecules

A

expression

36
Q

made of adenine linked to 3 phosphates. main energy of cells.

A

ATP

37
Q

chemical reaction: binds to enzymes which then breaks off a phosphate releasing energy/heat

A

ATP -> ADP + P
