Life Processes At Cellular Level

Question 1

Reactants needed for photosynthesis

Answer 1

Co2- enters plants through stomata diffuse from high to low
H2O- enters through roots. Osmosis high to low

Question 2

Stroma

Answer 2

See through to allow light to pass through the stroma speeds up the rate of reaction

Question 3

Thylakoid membrane

Answer 3

Arranged in stacks called grana
This maximises surface area which maximises the amount of chlorophyll which maximises the amount of light absorbed maximising the amount of glucose created

Question 4

Enzymes

Answer 4

Speed up the rate of reaction chain of amino acids they have an active site that binds to a specific substrate

Question 5

Light depending and light independent reactions

Question 6

Co factors

Answer 6

A co factor binds to an active site so the substrate can fits the active site

Question 7

Pollutants

Answer 7

Blocking nutrient therefore denature reducing the rate of reaction therefore photosynthesis is reduced and less growth

Question 8

Purpose of cellular respiration

Answer 8

To give us energy ATP this helps us complete cellular funtion

Question 9

Aerobic

Answer 9

Presence of oxygen produces most energy occurs in the mitochondria filled with enzymes
Glucose+O2=CO2+Water+34ATP

Question 10

Anaerobic

Answer 10

Glucoses occurs in cytoplasm
Glucose=lactic acid+2ATP

Question 11

Lactic acid

Answer 11

Inhibits enzymes
