Base
Phosphate group
Pentose (5-carbon) sugar
What is the result of translation? - Answers - Protein
A person has been jogging for 30-minutes at a relaxing pace. What substrates are being
used to make ATP? - Answers - Fats and glucose
What is the function of the Electron Transport Chain (ETC)? - Answers - Using high
energy electrons to power the production of ATP
Which molecules can be used for energy by the human body? (Select all that apply): -
Answers - Carbohydrates
Lipids
Creatine phosphate
Amino acids
What type of proteins do the ribosomes attach to the endoplasmic reticulum form?
(Select all that apply): - Answers - Lysosomal Proteins
Secreted proteins
Transmembrane proteins
Tunicamycin is an antibiotic that blocks the transfer of sugars onto amino acids during
glycosylation.
Which organelle would be affected by this antibiotic? - Answers - Golgi apparatus
Aquaporins are proteins that span the phospholipid bilayer of cells.
What protein structure is most likely associated with the transmembrane portion of the
aquaporin channels? - Answers - An amino acid chain with hydrogen bonds formed
between the peptide bonds
What is the name of the motor protein associated with actin filaments? - Answers -
Myosin
Why does water have a dipole moment? - Answers - Oxygen is more electronegative
and pulls electrons from hydrogen.
, A membrane with channels only permedable to water separates two solutions. The left-
side contains 30 mM NaCl which dissociates completely; the right side contains 30 mM
glucose which doesn't dissociate. What statement is correct? - Answers - Water will
move from the right side to the left side.
What is characteristic of hydrogen bonding? (Select all that apply): - Answers - Base
pairing between two strands of DNA
Determines secondary structure of proteins
Permits bases in RNA to bind to bases in DNA during transcription
What process begins after the small ribosomal subunit scans the mRNA and reaches a
start codon (AUG)? - Answers - Translation
What statements regarding DNA replication are true? (Select all that apply). - Answers -
DNA replication occurs during cell division
DNA strands are separated by helicase
What is the function of glycolysis? - Answers - Breakdown of a 6-carbon glucose to two
3-carbon pyruvate molecules
Cleaving one phosphate group off of which molecules will provide the most energy? -
Answers - ATP (adenosine triphosphate)
To which end(s) do proteins add during the synthesis of microtubules? - Answers - (+)
end
Botulinum toxin is a protease that cleaves vesicular associated membrane protein
(VAMP) into smaller pieces, rendering it nonfunctional. What will occur due to exposure
to botulinum toxin? - Answers - Disruption of the formation of the SNARE complex
What type of coat protein is needed at the endoplasmic reticulum membrane for
endocytic vesicle formation? - Answers - COPII
What contributes to the surface tension of water? (Select all that apply). - Answers -
Water molecules that are not at the air-water interface experience forces from all
directions
Water molecules at the air-water interface experience sideward and downward forces
Water molecules are in constant motion
Capsaicin is known as the "spicy molecule." After eating something spicy, you reach for
a cup of water to wash away the spiciness, but it does nothing to curb the burn. What
can you assume about the properties of capsaicin? - Answers - Hydrophobic
What accounts for 90% of skin changes in aging? - Answers - Sun exposure
