Biology 1100 Exam 2 Questions and
Correct Answers
1) Send sugar to mitochondria for conversion to ATP
2) Store as starch
3) Manufacture cellulose for growth ✅What are three things plant cells can do with the
glucose molecules they produce?
Carbon dioxide, sunlight energy, & water. Glucose & oxygen ✅What materials are
needed for photosynthesis & what materials are produced?
Solar energy. Chloroplasts ✅In what form is energy before and after the process of
photosynthesis? Where in plants does this process occur?
Destruction of the upper atmospheric layer of ozone gas, caused by substances formed
from breakdown of ozone depleting substances. Ozone depletion can be prevented by
limiting the use of private vehicles, making use of Eco-friendly cleaning products for the
home, avoiding the use of pesticides and banning the use of nitrous oxide. ✅What is
ozone depletion? What causes this? What can be done to minimize this phenomenon?
Cooler and shorter days trigger an end to auxin production, allowing the abscission
layer to grow and cut off the circulation of water, nutrients and sugar to the leaves.
✅Why do leaves change colors in the fall?
As electrons pass through the carriers from a higher-energy to a lower-energy state,
energy is released & used for ATP synthesis ✅What does an electron transport chain
do?
Glycolois is needed, carbon dioxide & water is produced. Eukaryotic cells ✅What is a
general reaction that indicates the process of aerobic cellular respiration? What is
needed and what is produced as a result of this process? What type of cells are capable
of this process?
Glycolosis ✅What is the name of the initial breakdown process all organisms begin
with to harvest the energy in food?
The net result of this cycle of reactions is the oxidation of an acetyl group to two
molecules of CO2, along with a transfer of electrons to NAD+ & FAD & a gain of one
ATP. Cycle turns twice per glucose molecule ✅What happens during the citric acid
cycle?
Oxygen picks up the electrons, along with H+ ions. This forms Water. ✅What molecule
picks up energy-depleted electrons at the end of the ETS?
, Animal cells convert pyruvate to lactate, occurs when O2 is not available. Plant cells &
yeast. Ethanol & carbon dioxide. ✅What is fermentation? What organisms ferment?
What do they produce as a by-product of fermentation?
When oxygen is not available. Lactate ✅Under what circumstances might human
muscles cells convert to fermentation? What is a by-product of this process in human
muscle cells?
Fermentation does not need oxygen, and breaks down glucose to lactic acid or ethanol
and CO2. Fermentation releases only 2 ATP per molecule of glucose. Aerobic
respiration breaks down glucose to CO2 with release of 36 ATP. Aerobic respiration
requires oxygen ✅What are three ways that aerobic cellular respiration and
fermentation differ?
Some wavelengths of visible light are absorbed by the photopigments chlorophyll a & b
& carotenoids ✅Explain the nature of visible light & how we interpret color
... ✅Describe what happens in a photosystem when sunlight energy hits it
Light-dependent reactions: Produce ATP & NADPH, light-independent reactions:
molecules from other reaction are used in the stroma to reduce carbon dioxide to a
carbohydrate ✅Summarize what happens during the light-dependent as well as the
light-independent reactions of photosynthesis
Mitochondria. ✅Where in cells does aerobic cellular respiration occur? In what form is
the energy before and after this process?
Separates internal from external environments of the cell. ✅What is the basic structure
of the cell membrane?
The channel protein allows a particular molecule or ion to cross the plasma membrane
freely. The carrier protein selectively interacts with a specific molecule or ion so that it
can cross the plasma membrane. The receptor protein allows molecules to bind to it
✅What are some functions of membrane proteins?
Movement of molecules from a higher to a lower concentration. Diffusion of water
across a membrane ✅What is diffusion? What is osmosis?
Solution ✅Fluid that contains a dissolved solid
Solvent ✅thing in higher concentration in a solution
Solute ✅thing in lesser concentration in a solution
