Alternative versions of proteins often have similar functions. T/F False
One common feature with G-protein coupled, enzyme-linked, and growth factor receptors is
that their activation leads to activation of protein kinases. T/F True
A key is placed into a keyhole then turned and the door opens. Which of the following
components of cell signaling would best correspond to the keyhole? the receptor
You discover a new sunflower that has blue flowers instead of yellow. When you cross this blue
variety with a common yellow variety you get blue and yellow variety you get blue and yellow
speckled flowers. What type of inheritance pattern does this gene exhibit? co-
dominance
The binding (or fusion) of vesicles to target membranes require which of the following?
SNARE (proteins)
Which of the following is NOT part of the endomembrane system? chloroplast
Which of the following is NOT a process of aerobic respiration? lactate fermentation
If oxygen is present, pyruvate will be converted to acetyl CoA in the mitochondrial matrix. T/F
True
, Which would be TRUE if a metabolic poison were to completely inhibit the function of
mitochondrial ATP synthase? pH difference across the inner mitochondrial membrane
would increase
These are short amino acid sequences that direct proteins to their correct location within the
cell. sorting signals
Which of the following is NOT a principle component that underlies cell organization?
semiautonomous nature
Molecular machines motors, switches, myosin, kinesin, flagella
This molecular machine operates in prokaryotes, chloroplasts, and mitochondria.
Molecular motor
Which of the following is NOT true for ATP? used ATP is discarded by the cell as waste
Which molecule is directly responsible for breaking down cAMP to inactive AMP?
phosphodiesterase
