Photosynthesis and Cellular respiration Flashcards
- Describe the ATP cycle
a. ATP becomes ADP +P when energy is released
- Describe the efficiencies of cellular respiration and fermentation
a. Cellular respiration creates 36 usable ATP (38 total) and fermentation only 2.
- What are the 3 stages of cellular respiration (put in correct order)? How many NET ATP’s produced in each?
a. Glycolysis (2 ATP made and 2 spent) (in cytoplasm)
b. Krebs Cycle (2 ATP) (in mitochondrion)
c. Electron Transport Chain (34 ATP) (in mitochondrion)
- Where do the stages of cellular respiration occur?
a. Glycolysis (2 ATP made and 2 spent) (in cytoplasm)
b. Krebs Cycle (2 ATP) (in mitochondrion)
c. Electron Transport Chain (34 ATP) (in mitochondrion)
- Explain the evidence that supports plants performing cellular respiration.
a. Carbon dioxide levels will increase when cellular respiration is occurring (without photosynthesis occurring)
- What is the advantage of mitochondria having cristae (folded inner membrane)?
a. Increases surface area where steps 1 and 2 of cellular respiration can occur.
- What is ATP used for in cells?
a. Active transport
b. Mechanical movement like muscle contraction
c. Building large molecules like proteins through dehydration reactions
- Know the products and reactants of cellular respiration (balanced equation in words and chemical formula).
a. C6H12O6 + 6O2 -> 6CO2 + 6H2O
- What are the parts of an ATP molecule?
a. Adenine, ribose, triphosphate tail
- What happens when the phosphate is broken off from the ATP molecule?
a. Energy is released
- What cellular process allows bread to rise?
a. Alcohol fermentation
- Describe the relationship between photosynthesis and cellular respiration.
a. Opposite reactions
- What causes muscle fatigue?
a. Lactic acid fermentation
- Making yogurt requires what kind of fermentation?
a. Lactic acid fermentation
- Describe the process of photosynthesis.
a. Carbon dioxide and water are consumed and powered by sunlight glucose and oxygen are produced
