B4 - Bioenergetics Flashcards
What type of reaction is photosynthesis?
Endothermic
What is the equation for photosynthesis?
Carbon Dioxide + Water -Light, Chlorophyll-> Glucose + Oxygen
What is the balanced symbol equation for photosynthesis?
6 CO2 + 6 H2O -Light, Chlorophyll-> C6H12O6 + 6 O2
How does the plant get carbon dioxide for photosynthesis?
Diffuses into the leaf through the stomata
How does the plant get water for photosynthesis?
Taken up the roots and transport to the leaves through the xylem
What are the limiting factors of photosynthesis?
Temperature
How does temperature affect the rate of photosynthesis?
The higher the temperature, the more kinetic energy that particles have so carbon dioxide and water move faster so increases the likelihood of collisions between reactants and enzymes
How does light intensity affect the rate of photosynthesis?
The higher light intensity, the more energy it has. This will continue until some other factor levels the graph
How does carbon dioxide concentration affect the rate of photosynthesis?
More carbon dioxide, faster photosynthesis can occur until something else limits the rate
How does chlorophyll affect the rate of photosynthesis?
More chloroplasts will affect the rate of photosynthesis. More chloroplasts means faster photosynthesis. Amount of chlorophyll can be affected by diseases, lack of nutrients, loss of leaves
