The Basics
What is the name given to organisms that can make their own food and the food for the biosphere?
autotrophs
Which process produces the most ATP per molecule of glucose?
c: aerobic respiration
True or False: ATP is not produced during photosynthesis; ATP is only produced during cellular respiration.
False
True or false: Cellular respiration is a single chemical reaction with just one step.
False
True or False: NAD+ is the empty bookbag; when filled it becomes NADH.
TRUE
Which bond in ATP releases energy when broken?
The bond between the second and third phosphate group
What is the result of glycolysis?
it converts glucose into two three-carbon compounds called pyruvate / pyruvic acid
Where does cellular respiration take place?
Where does photosynthesis take place?
First 2 groups!
1. Mitochondria
2. chloroplasts
How many ATP molecules are generated directly in glycolysis? (not net gain)
about 4
Mitochondria transfer ___________ energy from ____________________ to ATP.
1. Chemical energy
2. glucose
What are the products of cellular respiration? (3)
ATP, carbon dioxide, and water
What is the function of NADH in cellular respiration?
To carry high-energy electrons/ electron carrier
What is produced during the light reactions of photosynthesis? (3)
ATP, NADPH, O2
Which metabolic pathways is common in aerobic and anaerobic metabolism?
glycolysis
Chloroplasts transform_____________ energy into the chemical energy of ATP.
sunlight or light energy
What is an example of a molecule that is a reactant of photosynthesis and a product of cellular respiration?
CO2
What is the primary product of cellular respiration?
ATP
What is produced during the Calvin cycle/light independent reactions?
glucose, ADP, NADP+
The end products of the citric acid cycle include all of the following except
a:ATP
b:NADH
c:FADH2
d: pyruvate/pyruvic acid
d: pyruvate/pyruvic acid
What is the primary function of ATP in cells?
To store and release energy OR to power cellular activities.
The oxygen released into the air as a product of photosynthesis comes from
water
What is the chemical equation used to summarize cellular respiration
C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + ATP
The summary equation for photosynthesis is
6 CO2 + 6 H2O + sunlight → C6H12O6 + 6 O2.
How does ADP differ from ATP in terms of phosphate groups?
ADP has 2 phosphate groups where ATP has three phosphate groups
What is the function of pigments like chlorophyll in photosynthetic organisms?
to capture sunlight energy
