BIO 103 ACTUAL EXAMS COMPREHENSIVE
QUESTIONS AND ANSWERS SURE A+
✔✔Chlorophyll - ✔✔a pigment present in the green parts of plants which absorbs
photons of light energy
✔✔In the chloroplast, sunlight excites an electron obtained from________The excited
electrons are captured by_______and used to build up sugar molecules. - ✔✔water,
electron carriers
✔✔Which statements about fossil fuels are true? - ✔✔The energy present in fossil fuels,
such as coal, resulted from ancient photosynthesis., Fossil fuels are considered
nonrenewable because they take millions of years to create by natural processes., The
burning of fossil fuels increases the net CO2 in the earth's atmosphere.
✔✔sunlight - ✔✔the light reactions of photosynthesis
✔✔carbon dioxide - ✔✔the Calvin cycle
✔✔water - ✔✔the light reactions of photosynthesis
✔✔Calvin Cycle - ✔✔the electron carrier, NADPH, when it is carrying electrons
✔✔essential nutrients - ✔✔a substance that cannot be produced (synthesized) by the
organism and so must be obtained through the diet
, ✔✔The Energy of Activation - ✔✔what is lowered by an enzyme to make a reaction
possible, as when an enzyme brings two reactants very close together to allow a
covalent bond to form
✔✔exergonic reactions - ✔✔reactions that produce energy, as in the hydrolysis of ATP
✔✔Catabolic reactions - ✔✔reactions that break down complex substances into simpler
components, as in a hydrolysis reaction
✔✔What are the outputs for photosynthesis? - ✔✔sugar, oxygen
✔✔Why is lactic acid produced during fermentation? - ✔✔To regenerate electron carrier
molecules (NAD+) so that glycolysis can proceed and produce ATP
✔✔Order the phases of cellular respiration in a eukaryotic cell. - ✔✔glycolysis --> citric
acid cycle ---> electron transport chain
✔✔Which of the following suggest that glycolysis evolved early in the history of life on
earth? - ✔✔Glycolysis is the first step of both fermentation and cellular respiration,
Glycolysis occurs in the cytoplasm of all cells, Oxygen is not directly required for
glycolysis
✔✔What are the inputs for cellular respiration? - ✔✔sugar, oxygen
✔✔Anything that prevents ATP formation will most likely________ - ✔✔result in cell
death.
✔✔In the mitochondria, electrons power_______, to build up a concentration gradient
of_________ - ✔✔active transport, H+
✔✔citric acid cycle - ✔✔mitochondria
✔✔Glycolysis - ✔✔cytoplasm
✔✔Electron Transport Chain - ✔✔mitochondria
✔✔Fermentation - ✔✔cytoplasm
✔✔The core theme of biology, which explains both the unity and diversity of life, is -
✔✔evolution
