Photosynthetic organisms get energy from
inorganic substances
light
autotrophs
heterotrophs
Which of the following corrrectly sequences the flow of energy?
bacteria, fungus, rabbit
bacteria, sun, flower, deer
sun, grass, rabbit, fox
sun, hawk, mouse
The production of ATP during photosynthesis requires
energy released when hydrogen ions move down their concentration gradient
a carrier protein to catalyze the addition of a phosphate group to a molecule of ADP
energy from electrons passing through electron transport chains
all of the above
ATP molecules
produce NADPH
contain five phosphate groups
can both store energy and provide it for metabolic reactions
help a plant produce carbon dioxide
In glycolysis,
aerobic processes occur
four ATP molecules are produced
four ADP molecules are produced
glucose is produced
Carbon dioxide fixation in the Calvin cycle requires
ATP and NADPH
ATP and NADP+
ADP and NADPH
ATP and oxygen
The equation above summaries the overall process of
cellular respiration
photosynthesis
the Calvin cycle
the Krebs cycle
Which of the following environmental factors does NOT directly influence the rate of photosynthesis
light intensity
oxygen concentration
carbon dioxide concentration
temperature
For each molecule of glucose entering glycolysis, there is a net gain of
six ATP molecules
four ATP molecules
three ATP molecules
two ATP molecules
Aerobic respiration follows glycolysis when ________________ is available.
carbon dioxide
oxygen
hydrogen
water
If no oxygen is available to accept electrons during aerobic respiration,
aerobic processes stop
fermentation proceeds
only small amounts of ATP can be produced
all of the above
Which of the following is NOT a fuel used for cellular respiration?
carbohydrates
fats
proteins
water
Electrons in pigment molecules become excited
when light strikes a thylakoid
when water molecules are broken down
during light-independent reactions
during the Calvin cycle
The equation above summaries the overall process of
the Krebs cycle
photosynthesis
cellular respiration
the Calvin cycle
During cellular respiration,
the complete breakdown of glucose yields only carbon dioxide and water
the complete breakdown of glucose yields ATP molecules.
NADPH is produced
carbon dioxide is required.
The reaction that removes a phosphate group from ATP and results in ADP provides electrons for the cell.
True
False
Electrons and hydrogen ions combine with NADP+ in an electron transport chain to prodice NADPH.
True
False
The Calvin cycle produces ATP during the breakdown of a six-carbon molecule during cellular respiration.
True
False
In the third stage of photosynthesis, oxygen is used to make organic molecules.
True
False
Products of the Calvin cycle are three-carbon sugars that are used to produce organic compounds.
True
False
Carotenoids are yellow and orange plant pigments.
True
False
The less carbon dioxide available to a plant, the faster photosynthesis proceeds.
True
False
Metabolic processes that require oxygen are called anaerobic.
True
False
Fermentation allows the continued production of ATP even though oxygen is no longer present.
True
False
When glucose is broken down, two ATP molecules are used.
True
False
