Energy ⚡🪫
What is energy?
The ability to do work
What are the stacks of thylakoids called?
Grana
What is photosynthesis?
Autotrophs converting light energy into chemical energy.
What two energy-carrying molecules are produced during the light-dependent reactions?
ATP AND NADPH
What is another name for the Calvin Cycle
The light-independent reactions
What is the biological molecule that stores chemical energy in cells?
Adenosine triphosphate (ATP)
Which pigment reflects yellow, orange, and red light?
Carotenoids
Would photosynthesis be endothermic or exothermic?
Endothermic
What is another name for the light-dependent reactions?
Light reactions.
Where does the Calvin Cycle take place?
The stroma of the chloroplast.
What is ATP when it runs out of energy?
ADP
Why do plants appear green to our eyes?
Chlorophyll reflects green light and absorbs most other colors.
In what organelle does photosynthesis occur?
The chloroplast
What protein allows H+ ions to move through the membrane and helps produce ATP?
ATP synthase
What happens to ATP and NADPH after their energy is used in the Calvin Cycle
They become ADP and NADP+
If ATP is known as a battery when it's fully charged, what is ADP?
Drained battery
What is the fluid-filled space outside the grana called?
Stroma
Which large molecule does photosynthesis build when absorbing light?
Glucose
What waste product is released when water is split?
Oxygen
Why can't ATP and NADPH store energy for long periods of time?
They are not stable enough for long-term energy storage
What is ATP chemical energy converted into when doing exercise?
Mechanical energy
Why would a plant with very little chlorophyll have difficulty surviving?
It would absorb less light energy, reducing photosynthesis and glucose production
Two stages of photosynthesis?
Why is NADPH needed during photosynthesis?
It carries high-energy electrons to the Calvin Cycle
What would happen to the glucose production for the plant if Calvin cycle stopped?
Glucose would no longer be produced because the Calvin Cycle is the stage that forms glucose
