B4 - Bioenergetics

Question 1

What type of reaction is photosynthesis?

Answer 1

Endothermic

Question 2

What is the equation for photosynthesis?

Answer 2

Carbon Dioxide + Water -Light, Chlorophyll-> Glucose + Oxygen

Question 3

What is the balanced symbol equation for photosynthesis?

Answer 3

6 CO2 + 6 H2O -Light, Chlorophyll-> C6H12O6 + 6 O2

Question 4

How does the plant get carbon dioxide for photosynthesis?

Answer 4

Diffuses into the leaf through the stomata

Question 5

How does the plant get water for photosynthesis?

Answer 5

Taken up the roots and transport to the leaves through the xylem

Question 6

What are the limiting factors of photosynthesis?

Answer 6

Temperature

Question 7

How does temperature affect the rate of photosynthesis?

Answer 7

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

Question 8

How does light intensity affect the rate of photosynthesis?

Answer 8

The higher light intensity, the more energy it has. This will continue until some other factor levels the graph

Question 9

How does carbon dioxide concentration affect the rate of photosynthesis?

Answer 9

More carbon dioxide, faster photosynthesis can occur until something else limits the rate

Question 10

How does chlorophyll affect the rate of photosynthesis?

Answer 10

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
