BIO 1050 ACTUAL EXAM SOLVED
QUESTIONS COMPLETE PREPARATION
RESOURCE
●● In type 2 diabetes
Answer: the body does not respond to insulin as well as normal
●● During oxidative phosphorylation of cellular respiration
Answer: a concentration gradient of hydrogen ions is made then used to
make ATP
●● Why is oxidative phosphorylation logically last when a molecule of
glucose is processed by cellular respiration?
Answer: Oxidative phosphorylation processes the energy in NADH and
FADH2, which was made in the earlier stages, into ATP
●● ATP is important to life because it
Answer: is the main type of chemical energy directly coupled to cellular
reactions, like muscle contraction
●● An enzyme
Answer: makes the reaction it catalyzes, more likely to occur
, ●● Which of the following is most likely to be endergonic?
Answer: making a bond between two carbon atoms
●● There is a hormone called calcitonin. Calcitonin reduces blood
calcium concentrations. Blood calcium concentration is maintained
under homeostatic control. When would you expect the endocrine
system to release calcitonin?
Answer: when the blood calcium concentration is above the homeostatic
range
●● Which of the following is NOT a type of membrane protein?
Answer: cytoskeleton proteins
●● Many organ systems work together with cellular respiration to
provide cells with ATP. Which phase of cellular respiration depends the
LEAST on the pulmonary system?
Answer: glycolysis
●● In which stage is food broken down into pieces small enough to be
absorbed?
Answer: digestion
●● A muscle contracts because
