Section 1

Question Answer
FunctionDetermines structure and function
How does the proteome determine function?Determining the types of proteins made, the relative amount of each protein, when the proteins are made
Specific conditions must be present exampleEx. Presence of a certain hormone
Not all genes within a genomeAre used at all times within a cell or organism
Different cell types in multicellular organismsAre determined by different subsets of the genome getting decided by the proteome. Therefore, determining cell structure and function
The proteome consists of Proteins. The set of expressed proteins in a cell or organism, at a given time, under specific conditions

Section 2

Question Answer
Enzymes are made of blank (example) and blank (example)non-protein parts such as cofactors and protein parts such as an active site
Active site featuresRegion where substrate binds to enzyme, must have specific shape or can't bind, undergoes chemical reaction after binding
Cofactor examplesMetal ions, coenzymes, prosthetic groups
Enzymes are sensitive topH and temperature
pHChanges in pH affect charges on AAs
TemperatureDenatures at high temperatures, less kinetic energy at low temperatures
Enzymes are influenced byCompetitive and non-competitive inhibitors
Competitive inhibitorsBlock the substrate from the active site
Non-competitive inhibitorsBind to the allosteric site
Enzyme function Catalyze and regulate reactions in the cell
How do enzymes work?Bind substrates
What are the features of a substrate?molecule of interest, must find enzyme with right shape
