CR1
What is the primary purpose of cellular respiration?
Make ATP!
Which has more energy, ADP or ATP?
ATP
where does the light reaction take place?
thylakoid
"photo" means...?
light!
photosynthesis, photograph, photon, etc.
True or false: only eukaryotes make ATP
false! Everything needs ATP!
what are the 3 main steps of aerobic cellular respiration? Which one makes the most ATP?
1) glycolysis 2) citric acid cycle and 3) electron transport chain - most ATP!.
True or false: bacteria prefer aerobic cellular respiration because it makes more ATP.
False, bacteria can't do aerobic CR because they don't have a mitochondria
What are 2 uses of glucose within the plant?
Energy (breakdown in cellular respiration) or structure (build cell walls to make stems, etc.)
What are the reactants (things needed) for photosynthesis?
water, carbon dioxide, and light energy
What are the 2 main organelles that make energy in eukaryotes?
Mitochondria and chloroplast!
_______ + C6H12O6 → _________ + 6CO2 + ATP
Fill in the blanks
6 oxygen
6 H2O
Why would our bodies switch from aerobic respiration to anaerobic respiration?
Ran out of oxygen available in cells.
True or false: a product of the electron transport chain is lactic acid, and that is why you get sore after a lot of exercise.
False, its a product of fermentation
An aquatic plant is producing more and more bubbles the closer it is to a light source. Explain what's in the bubbles and why this relationship happens?
Oxygen is in the bubbles. The closer the plant is to light, the more photosynthesis it can do (photosynthesis requires light). Since photosynthesis makes oxygen, there will be more oxygen bubbles if more photosynthesis happens.
____________ is endothermic and ______________ is exothermic
photosynthesis is endothermic and cellular respiration is exothermic
What happens in glycolysis?
1) glucose is broken down into pyruvate
2) a little bit of ATP is made
happens in the cytoplasm and is anaerobic
What is fermentation?
- Step 2 in anaerobic respiration
- Fermentation allows glycolysis to loop so more ATP can be made quickly
- Lactic acid/Alcohol is made depending on who is doing it.
Is photosynthesis aerobic or anaerobic, explain why or why not.
Anaerobic because it does not require oxygen. Oxygen is produced, but not something that is needed.
Explain what is happening during the Calvin cycle? Include the location and a product that is made.
1) CO2 absorbed through the stomata (leaf pores)
2) ATP is used to break apart CO2 molecules
3) ATP is used to build a glucose molecule
4) happens in the stroma
In a closed water bottle there is water, a snail, aquatic plant, and gravel. What are the sources of carbon dioxide in the water bottle?
snail and plant (both doing cellular respiration)
What are 3 things going on during the electron transport chain
1) active transport of H+
2) water is being made
3) passive transport of H+ thru ATP synthase
4) a lot of ATP is made
5) electrons being transported
When does ADP become ATP?
In the final stage of making ATP, a 3rd phosphate is added to ADP making it into ATP (high energy). When it's time to use the ATP energy, the bond is broken and ATP is back into ADP (low energy).
Explain what is happening during the light reaction? Include where it takes place and a byproduct that is produced
1) light energy is absorbed
2) the light energy is used to break apart water molecules
3) oxygen is released as byproduct, and a little ATP is made
4) happens in the thylakoid.
A plant grew 10 pounds in mass. Where did the plant get the materials to grow more plant matter?
CO2 taken in from the atmosphere and H2O taken in through the roots. These get converted to glucose during photosynthesis, which is used to make more plant matter.
What is the name of the enzyme/protein channel at the end of the electron transport chain, where the most ATP is made?
ATP Synthase (synthesis = to make or build)
