A1. Explain the relationship between producers (autotrophs) and consumers (heterotrophs)
|
Producers (autotrophs): convert solar energy to chemical energy.
Consumers (heterotrophs): live off of chemical energy. |
|
|
A2. Explain the relationship between photosynthesis and cellular respiration
|
Products of cellular respiration are reactants in photosynthesis!
Products of photosynthesis are reactants in cellular respiration! |
|
|
A3. Provide the formulas for cellular respiration and photosynthesis
|
Photosynthesis = 6CO2 + 12H2O + light --> C6H12O6 + 6H2O + 6O2
Cell.Resp. = C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP |
|
|
A4. Define oxidation and reduction. Explain what a redox reaction is, and for both photosynthesis and cellular respiration, state which molecules are reduced and which are oxidized.
|
Oxidation: Loss of an e-, delta charge is +1
Reduction: Gain of an e-, delta charge is -1 Often associated with gain/loss of H+ ion. Redox rxn = One molecule is oxidized while other is reduced. (often due to xfer of H+ ion) C.R.: Glucose is oxidized, O2 is reduced. Ptsyn.: ? is oxidized, ? is reduced. |
|
|
A5. In one sentence, what occurs during cellular respiration?
|
Glucose is repeatedly phosphorylated, broken down and E is released.
