BIO 152 Exam 3 UKY UPDATED Exam
Questions and CORRECT Answers
cellular respiration - CORRECT ANSWER - Process that releases energy by breaking
down glucose and other food molecules in the presence of oxygen and absorbing into the blood
stream/to other cells
makes ATP
Ventilation - CORRECT ANSWER - movement of air into and out of the lungs
Gas exchange - CORRECT ANSWER - the diffusion of O2 and CO2 between air or water
and the blood at the respiratory surface
Circulation - CORRECT ANSWER - Transport of gas to/from body cells
formula for cellular respiration - CORRECT ANSWER - C6H12O6 + 6 O2 -> 6CO2 +
6H20 + ENERGY (ATP)
4 steps of cellular respiration - CORRECT ANSWER - 1. Glycolysis
2. Pyruvate processing
3. Citric acid cycle
4. Electron transport and chemiosmosis
Reduction - CORRECT ANSWER - gain of electrons
loose O gain H
Oxidation - CORRECT ANSWER - loss of electrons
gain O Loose H
, Glycolysis - CORRECT ANSWER - first step in releasing the energy of glucose, in which
a molecule of glucose is broken into two molecules of pyruvic acid
aerobic and anaerobic processing of making ATP
Pyruvate Oxidation - CORRECT ANSWER - 2nd step in cellular respiration occurs on the
way to the mitochondrial matrix. Pyruvate is oxidized into 1 CO2, 1 NADH, 1 acetyl-COA (2
carbons attached to coenzyme A)
Citric Acid Cycle - CORRECT ANSWER - Completes the breakdown of glucose by
oxidizing a derivative of pyruvate to carbon dioxide.
ATP, NADH, FADH2 produced
oxidative phosphorylation - CORRECT ANSWER - The production of ATP using energy
derived from the redox reactions of an electron transport chain; the third major stage of cellular
respiration
electrons move down the chain releasing energy and pumping protons out of gradiant
substrate-level phosphorylation - CORRECT ANSWER - The enzyme-catalyzed
formation of ATP by direct transfer of a phosphate group to ADP from an intermediate substrate
in catabolism.
Krebs cycle - CORRECT ANSWER - pyruvic acid is broken down into carbon dioxide in
a series of energy-extracting reactions
Carbohydrates - CORRECT ANSWER - Broken down to simple sugars
Fats - CORRECT ANSWER - broken to glycerol and fatty acids, glycerol into glycolysis
Proteins - CORRECT ANSWER - Nutrients the body uses to build and maintain its cells
and tissues
