Bioenergetics Flashcards
Photosynthesis equation (word & symbol )
Carbon dioxide + water —> Glucose + oxygen
6CO2 + 6H2O —> C6H12O6 + 6O2
Light in the middle
Symbol for glucose
C 6 H 12 O6
Ways that plants use glucose
For respiration
Make cellulose
Making amino acid
Stored as oil or fat
Store as starch
Limiting factor affect the rate of photosynthesis 3
Light intensity
The concentration of CO2
The temperature
Equation measuring light intensity
Light intensity = 1/distance (d2)
Unit (a.u.)
Respiration is not breathing
Respiration
It is the process of transferring energy from glucose, which goes on in every cell
Is exothermic
Metabolism
The sum/total of all of the reaction that happened in a cell or the body
Two type of respiration
Aerobic respiration
Anaerobic respiration
Aerobic respiration
Respiration using oxygen
Most efficient way to transfer energy from glucose
Happen inside mitochondria
Aerobic respiration equation
Glucose + oxygen —> carbon dioxide + water
C6H12O6 + 6O2 —> 6CO2 + 6H2O
Anaerobic respiration (animals)
Used if there is not enough oxygen (ex: exercising)
It is the incomplete breakdown of glucose , making lactic acid
Does not transfer nearly as much energy aerobic respiration because the glucose is not fully oxidised (because it doesn’t combine with oxygen)
It is only useful for emergencies
Anaerobic respiration equation (animal)
Glucose —> lactic acid
Anaerobic respiration (plants)
They produce ethanol(alcohol) and carbon dioxide instead of lactic acid
It happens in plants in yeast cells
Anaerobic respiration happen in yeast cell called fermentation
Oxygen debt
It is the amount of extra oxygen your body needs to react with the buildup of lactic acid and remove it from the cell
