What important molecule is made when H+ ions pass through ATP synthase and go back to the matrix?
Atp
equation for cell respiration words
glucose+oxygen->carbon dioxide+water+energy
equation for cell respiration chemical formula
C6H12O6 +O2 → CO2 + H2O+ energy
What is the difference between aerobic and anaerobic respiration?
Aerobic uses oxygen anaerobic doesn’t
What is the difference between lactic acid fermentation and alcoholic fermentation?
lacf makes lactic acid molecules Af makes ethyl alcohol and carbon dioxide.
What is photosynthesis?
turning sunlight into energy
In which organelle does photosynthesis occur?

Chlorophyll
What is a single disc located within a chloroplast called?
Thylakoid
What is a stack of discs located within a chloroplast called?
Granum
What is the central space (filled with liquid) located within a chloroplast called?
Stroma
Which part of photosynthesis occurs in the thylakoid discs?
Light reactions
Which part of photosynthesis occurs in the stroma?
Calvin cycle
In the light reactions, what molecule do you start with (the reactant)?
Carbon dioxide?
In the light reactions, what molecule do you end with (the product)?

Hydrogen ions?
What is the name of the big enzyme that H+ ions pass through when they go back to the stroma?
ATP synthase
In which phase of photosynthesis is light used for its energy?
Light reaction
In which phase of photosynthesis is water used (it split apart for its electrons)?
Lights reaction
Why are most leaves broad and flat?
absorb sunlight
Using words, state the equation for photosynthesis.
6CO2 + 6H2O → C6H12O6 + 6O2
Using chemical formulas, state the equation for photosynthesis.
6CO2 + 6H2O → C6H12O6 + 6O2
why are thylakoid discs flat
absorb sunlight
Why is the inner membrane of mitochandria so folded up?
more atp production
What does alcohol fermentation produce
ethanol, carbon dioxide, and NAD+
what does lactic acid fermentation produce
lactic acid (lactate) and NAD+
