OAT Booster- Biology Cell and Molecular
Biology (Pro- Tips) Study Guide Test.
What are the three disaccharides? - CORRECT ANSWER sucrose, lactose, and maltose
What are the two components of sucrose? - CORRECT ANSWER glucose + fructose
What are the two components of lactose? - CORRECT ANSWER glucose + galactose
What are the two components of maltose? - CORRECT ANSWER glucose + glucose
Enzymes are almost always considered to be __________ - CORRECT ANSWER proteins
But sometimes RNA can act as an___________ - CORRECT ANSWER enzyme (example- ribozymes)
Reverses a protein to its primary structure - CORRECT ANSWER protein denaturation
Eliminates all protein structure, including the primary structure - CORRECT ANSWER protein digestion
Pyramidines - CORRECT ANSWER cytosine, uracil, thymine
(CUT the PYE)
Purines - CORRECT ANSWER Adenine and Guanine
(PUre As Gold)
Differential configuration forms..... - CORRECT ANSWER continuous layers of sediment
, Where are insoluble proteins found in differential configuration? - CORRECT ANSWER They are found in
the pellet (bottom)
Where are soluble proteins found in differential configuration? - CORRECT ANSWER They remain in the
supernatant (the liquid above the pellet)
What are the functions of an enzyme? - CORRECT ANSWER They act as catalysts that lower the
activation energy of a reaction, thereby accelerating the rate of the overall reaction.
Functions vary based on pH and temperature
Active site binds substrates via induced fit.
Does active transport require ATP? - CORRECT ANSWER yes ATP is required
Does facilitated diffusion require ATP? - CORRECT ANSWER No because a concentration gradient has
been created. Only active diffusion requires ATP.
Peripheral membrane proteins are generally_______ (hydrophilic or hydrophobic)? - CORRECT ANSWER
hydrophilic (water loving)
What holds peripheral membrane proteins together? - CORRECT ANSWER They are held in place by:
H- bonding and
electrostatic interactions
How can you disrupt/ detach peripheral membrane proteins? - CORRECT ANSWER By changing the salt
concentration OR
the pH
Integral proteins are________ (hydrophilic or hydrophobic)? - CORRECT ANSWER hydrophobic (water
hating)
How can you destroy integral proteins? - CORRECT ANSWER by using detergent
