Photosynthesis and Cellular Respiration Flashcards
What are the reactants for photosynthesis? (what goes in)
Carbon dioxide and water
(6 CO2 and 6 H2O)
What are the products of photosynthesis?
(what comes out)
Glucose and Oxygen
(C6H12O6 and O2)
What are the reactants for cellular respiration?
(what goes in)
Oxygen and Glucose
(O2 and C6H12O6)
What are the products of cellular respiration?
Carbon Dioxide, Water, and ATP
(6CO2, 6H2O, and 36 ATP)
Why do plants appear green?
Because they reflect green light
(meaning they don’t absorb green light)
Which phase of photosynthesis takes place in the thylakoids?
The light dependent reactions
Where does the Calvin Cycle take place?
(Calvin Cycle = Light Independent Reactions)
In the Stroma of the Chloroplast
During the light dependent reactions, what causes the water molecules to split?
Light
Where does the Oxygen that plants release come from?
The splitting of water in the light reactions
What are the products of the light dependent reactions?
Oxygen, NADPH, and 2 ATP
What goes into the calvin cycle?
Carbon Dioxide, NADPH, and ATP
What is produced through the calvin cycle?
Glucose, NADP, and ADP
What is the overall purpose of photosynthesis?
To make energy in the form of glucose
_____ is the form that energy is found in food
Calories (kilocalories)
What is the purpose of cellular respiration?
To make ATP (energy)
How many steps are in aerobic respiration? What are they?
Glycolysis, Kreb’s Cycle (Citric Acid Cycle), and the Electron Transport Chain
Where does glycolysis take place?
In the cytoplasm
What goes into glycolysis?
Glucose and 2 ATP
Is Glycolysis aerobic or anaerobic?
Anaerobic (does not require oxygen)
Pyruvic acid, NADH, and a net gain of 2 ATP are the products of ______ in cellular respiration.
Glycolysis
What molecules enter the Kreb’s cycle?
Pyruvic acid and oxygen
What is released from the Citric Acid Cycle?
CO2, NADH, FADH, and 2 ATP
Where do the 2nd and 3rd steps of respiration take place?
In the mitochondria
FADH, NADH, and Oxygen are all involved in the
Electron Transport Chain
How much ATP is made in the ETC?
32 ATP
How much ATP does cellular respiration create?
36 ATP
Where is the energy stored in an ATP molecule?
Between the 2nd and 3rd phosphate molecules
How much energy does fermentation produce?
0 ATP
How do lactic acid and alcoholic fermentation differ?
One makes lactic acid, the other makes alcohol
