GCU BIO-201 Exam 1 | Grand Canyon University – Complete Exam Review with Questions and Answers
- If a drug inhibits ATP synthase, what immediate effect would you expect
on cellular metabolism?
Decreased ATP production Increased glucose breakdown Enhanced protein synthesis Increased oxygen consumption
- Describe the role of NADH and FADH2 produced in the Krebs cycle in
cellular respiration.
NADH and FADH2 are used to synthesize proteins in the cell.NADH and FADH2 are converted into glucose for energy storage.NADH and FADH2 are waste products that are excreted from the cell.NADH and FADH2 carry energy to the electron transport chain, where it is used to produce ATP.
- What term describes the property of a hydrophilic head in biological
molecules?
Water fearing Hydrophobic Water loving 1 / 3
Nonpolar
- What is the definition of tertiary protein structure?
the arrangement of multiple polypeptide chains in a protein 2 / 3
the specific sequence of nucleotides in RNA linear sequence of amino acids in a protein three-dimensional folding pattern of a protein due to side chain interactions
- What type of carbohydrates are monosaccharides classified as?
complex carbohydrates disaccharides polysaccharides simple sugars
- Describe the role of RNA in protein synthesis.
RNA stores genetic information in the nucleus.RNA helps in the formation of cell membranes.RNA acts as a messenger that carries genetic information from DNA to the ribosomes for protein synthesis.RNA is involved in the breakdown of glucose during glycolysis.
- What is the definition of activation energy?
Energy that is needed to get a reaction started Energy used in cellular respiration Energy required for protein synthesis Energy released during a reaction
- What is the definition of a hypotonic solution?
Solute concentration is equal to inside the cell; cell remains unchanged
