photosynthesis and respiration

Question 1

factors affecting photosynthesis

Answer 1

light intensity, CO2 conc and temperature

Question 2

how does light intensity affect rate of photosynthesis

Answer 2

chlorophyll use light energy for photosynthesis, which can only be done as quickly as this energy is provided
increased LI: increases ROP until a certain point, after that CO2 or temp is limiting factor

Question 3

how does CO2 conc affect rate of photosynthesis

Answer 3

as CO2 increases, so does rate of photosynthesis.
at a certain conc, rate will stop increasing as temp or light are the limiting factors

Question 4

how does temperature affect rate of photosynthesis

Answer 4

as temp increases, so does rate of photosynthesis, because the particles have more kinetic energy, making more frequent successful collisions between the enzyme and substrate. however past around 45 degrees, the enzyme’s active sites denature, so the substrate is no longer complimentary, so the rate rapidly decreases.

Question 5

aerobic respiration word equation

Answer 5

glucose + oxygen = CO2 + water (+ energy)
- reverse of photosynthesis
- lots of oxygen available
- most efficient way to transfer energy from glucose

Question 6

aerobic respiration symbol equation

Answer 6

C6H12O6 + 6O2 = 6CO2 + 6H2O

Question 7

anaerobic respiration word equation

Answer 7

• releases much less energy

Question 8

photosynthesis symbol equation

Answer 8

6CO2 + 6H2O = C6H12O6 + 6O2

Question 9

respiration

Answer 9

process of transferring energy from glucose
from ADP to ATP
