Photosynthesis Basics
This specific type of organism makes its own food using sunlight.
4.3.1 Day 1
Photoautotroph
Gas enters and exits leaves through these structures.
4.3.1 Day2
Stomata
This specific process oh photosynthesis removes CO₂ from the atmosphere.
4.2.2 Day 1
Carbon fixation during photosynthesis
The main purpose of cellular respiration.
4.3.1 Day 1
To release energy from glucose and make ATP
Products of alcohol fermentation.
4.3.2
Ethanol + carbon dioxide
These two molecules are the reactants of photosynthesis.
4.3.1 Day 1
Carbon dioxide + water
In chloroplasts, light‑dependent reactions occur in these stacked structures.
4.2.1 Day 1
Thylakoids (organized in grana)
These organisms in the ocean provide about half of Earth's oxygen.
4.2.2 Day1
Phytoplankton
The reactants of cellular respiration.
4.3.1 Day 1
Glucose + oxygen
Which group performs anaerobic respiration using molecules like sulfate instead of oxygen?
4.3.2
Methanogens
The green pigment that absorbs sunlight during photosynthesis.
4.3.1 Day2
Chlorophyll
Plants in dry climates often have this coating to reduce water loss.
4.2.2 Day 2
Waxy cuticle/covering
If phytoplankton populations sharply declined, what major atmospheric change would occur?
4.2.2 Day 1
Atmospheric oxygen would decrease significantly.
Which stage of respiration happens in the cytosol?
4.3.1 Day 2
Glycolysis
What by‑product causes "burning legs" during exercise?
4.3.2
Lactate (lactic acid)
The two major stages that photosynthesis is broken up into.
4.2.1 Day2
Light‑dependent reactions & light‑independent reactions
Which plant structures connect to transport glucose away from the leaf?
4.2.1 Day 1
Phloem vessels
What happens to photosynthesis if temperature becomes too high?
4.2.2 Day1
Enzymes stop working properly and photosynthesis slows or stops.
Why is cellular respiration considered an exothermic process?
4.3.1 Day 1
More energy is released forming CO₂ + H₂O than is used to break glucose + oxygen bonds
Explain why the equations for photosynthesis and respiration are considered opposites.
4.3.1 Day 2
The products of one are the reactants of the other.
Explain why photosynthesis is considered an endothermic process.
4.2.1 Day 2
It absorbs more energy to break reactant bonds than is released forming product bonds; extra energy is stored in glucose.
Why can’t plants create energy during photosynthesis?
4.2.1 Day 2
Energy is transformed from light to chemical; it cannot be created.
What law is supported by the fact that atoms in photosynthesis are simply rearranged?
4.2.1 Day 2
The law of conservation of matter
Explain how the ETC (electron transport chain) depends on earlier stages of respiration.
4.3.1 Day 2
It uses NADH & FADH₂ from glycolysis and the Citric Acid cycle to power ATP production.
Difference between facultative and obligate anaerobes.
4.3.2
Facultative anaerobes switch between aerobic & anaerobic processes.
Obligate anaerobes can survive only without oxygen.
