Respiration Flashcards
List 3 things we need energy to do.
Control body temp.
For chemical reactions.
For movement.
What is the word and symbol equation for aerobic respiration?
Glucose + oxygen → carbon dioxide +water.
C6H12O6 + 6O2 → 6CO2 + 6H2O
What is the word equation for anaerobic respiration?
Glucose → lactic acid
What is the word equation for fermentation?
Glucose → ethanol + carbon dioxide.
Define oxygen dept.
It is the amount of oxygen which must be taken in to convert all the lactic acid to carbon dioxide.
What is lactic acid?
It’s the by-product of anaerobic respiration which causes muscle cramp.
What are the 3 factors that affect fermentation?
Temperature.
Glucose concentration.
Density of yeast.
What is the word and symbol equation for photosynthesis?
Carbon dioxide + water → oxygen + glucose.
6CO2 + 6H20 → C6H12O6 + 6O2
What is the equation for a light dependent reaction?
H2O → 2H+ + 2e- + 1/2 O2
What is the equation for a light independent reaction?
2H2O → 4H+ +4e- + O2
Give 3 things glucose in respiration is used for.
Cellulose to form cell walls.
Proteins for growth and repair.
Starch food store.
What is the formula for the rate of photosynthesis?
Rate = I/time
What is the formula for relative light intensity?
1 / Distance from light source^2
