100
What is ATP?
Energy carrying molecule
100
What type of organism undergoes photosynthesis
Photoautotroph (plants, algae, cyanobacteria)
100
What is ATP synthase
Channel protein that uses Hydrogen ions gradient to make ATP from ADP and a phosphate.
100
Where does cellular respiration occur?
Mitochondria
100
What is the step or process that occurs before fermentation and/or cellular respiration?
Glycolysis
200
Where does the energy come from to make ATP?
Break down of molecules (digestion)
200
Where does photosynthesis happen?
Chloroplast.
200
How is the water molecule used the light-dependent reaction?
Splits into Hydrogen ions, electrons that are donated to the ETC and oxygen molecules.
200
What are the products of glycolysis
2 pyruvates, 2 NADH and 2 ATP
200
What is the requirement for cellular respiration to happen?
Oxygen
300
Explain how energy flows in a biological system
sunlight > chemical > heat
300
What are the reactants of photosynthesis?
R: Water and Carbon dioxide (and sunlight)
300
What are the products of the calvin cycle?
glucose
300
What is released as a waste product in the krebs cycle when producing many ATP, NADH and FADH2 molecules?
Carbon dioxide
300
What is fermentation?
Anaerobic process that allows glycolysis to continue by breaking down pyruvates and recycling NAD+.
400
What is METABOLISM
Combination of all reactions of an organism (breakdown + buildup of molecules)
400
Where does the calvin cycle occur
stroma
400
How are photosynthesis and cellular respiration related?
Products of photosynthesis are reactants of cellular respiration. Products of cellular respiration are reactants of photosynthesis.
400
Where exactly the krebs cycle and the ETC occurs?
Matrix and inner membrane of mitochondria.
400
What is product of lactic acid fermentation and in what kind of cells does it occur?
Lactic acid and muscle cells.
500
What is a chemoautotroph
Organisms use chemical energy instead of light energy to make energy storing molecules.
500
Name the molecule that absorbs sunlight energy and say its exact location.
Chlorophyll and thylakoid membrane
500
Why do plants undergo cellular respiration if they make chemical energy through photosynthesis?
They need to store the energy
500
Why is oxygen necessary for the production of ATP in cellular respiration?
Is the final electron acceptor of the ETC.
500
What is better? Fermentation or cellular respiration? (say why)
Cellular respiration produces more energy.
