BSC 1005 EXAM 2 Multiple Choice
Where in the cell does glycolysis occur?
cytoplasm
All cells have some characteristics in common; both prokaryotic and eukaryotic cells have
cytoplasm, a plasma membrane, and DNA.
The number of ATP produced during cellular respiration from one glucose molecule is
38
The light reactions act much as a battery to power the reactions of the Calvin cycle. This energy is stored as
ATP and NADPH.
The light reactions produce __________, which are used in the Calvin cycle. The Calvin cycle produces __________, which are in turn used in the light reactions.
ATP and NADPH; ADP and NADP
What type(s) of organisms does cellular respiration occur in?
All answers given are correct.
Which of the following organelles would form a membrane bound package also known as a vesicle?
Golgi apparatus
The O2 given off during photosynthesis is derived from which compound?
H2O
In photosynthesis, the light reactions ____________ while the Calvin cycle ____________.
capture solar energy; converts the captured energy to chemical potential energy
Chlorophyll is to the light reactions as ____________ is to the Calvin cycle.
RuBP
Why do plants contain other pigments besides chlorophyll?
The additional pigments are able to absorb other light wavelengths that chlorophyll cannot.
Susan suffered from a heart attack. When the doctors tested the heart muscle they found that she had an increased ratio of lactic acid to pyruvic acid in her heart. What does this say about the availability of oxygen in her heart muscle cells?
The heart cells had not received adequate oxygen supply.
On the cellular level what process uses oxygen to break food down, producing ATP?
cellular respiration
Energy is released from ATP when
a phosphate group is removed from ATP yielding ADP + P + energy.
ATP releases energy when
a phosphate is removed
The part of the enzyme into which the substrate fits is called the
active site
Which of the following organisms can perform photosynthesis?
algae
Mitochondria are found in
both plant cells and animal cells
Osmosis includes
both the diffusion of water and a semi-permeable membrane
A prokaryotic cell
does not have a membrane-bound nucleus.
Cellular respiration uses oxygen to convert the chemical energy stored in organic molecules into
energy in ATP.
Which of the following is the correct sequence of events in cellular respiration?
glycolysis→preparatory reaction→citric acid cycle→electron transport chain
Simple diffusion of molecules occurs
in nonliving systems as well as living systems
ATP is a good source of energy for a cell because
its breakdown is coupled with energy-requiring reactions.
Compared with a eukaryotic cell, a prokaryotic cell
lacks organelles beyond ribosomes.
A tadpole that is undergoing metamophosis into a frog and losing the need for a tail would see abundant numbers of what organelle to help assist in the tail loss.
lysosomes
What organelle is used during the process of cellular respiration?
mitochondria
Where within the cell is ATP built up?
mitochondria
Which of the following organelles would be abundant in a sperm cell that is seeking to fertilize an egg cell?
mitochondria
Which of the following is a CORRECT matching of an organelle and its function?
mitochondrion - cell respiration
Which of the following structures would NOT be seen in a prokaryotic cell?
nucleus
Which of the following is not a product of cellular respiration?
oxygen
Fermentation occurs if
oxygen is not present.
Which of the types of cellular activities listed below would not use ATP?
passive transport
Which of the following is not a type of potential energy?
the energy of a ball rolling down a hill
Inside the chloroplasts, chlorophyll is found in the
thylakoid membrane.
Cellular respiration is the opposite of what other cellular process?
photosynthesis
What must materials pass through to enter or leave a cell?
plasma membrane
Identify the organelle - function pairing that is INCORRECT.
plasma membrane - provides strength to plant cell walls
Both plants & animals need mitochondria to
produce ATP
