B4* Flashcards
What type of reaction is photosynthesis
Photosynthesis is an endothermic reaction
Equation for photosynthesis
Carbon. Dioxide + water— glucose + oxygen
What’s chlorophyll
Chlorophyll is the green pigment
It absorbs energy from light to convert the reactants to products
What’s starch
Starch is an insoluble
Stronger than glucose
Why do plants use glucose
Respiration- to convert the rest of the glucose into useful substances
Make cellulose- strength the wall l
To Make amino acids
Environmental factors the affects photosynthesis
Temperature
Light intensity
Carbon
How would the low rate of chlorophyll affect its rate of photosynthesis
The rate of photosynthesis decreases because chlorophyll cannot absorb energy
Why’s the rate of photosynthesis limited in winter
It’s limited in winter because there’s fewer hours of sunlight and temperatures limits
What would happen if the temperatures too high
Photosynthesis decreases and the enzyme as have become denatured
artificial methods for a plant to grow
Artificial sunlight
Constant temperature using ventilation paraffin heater to maintain co2
What type of reactants is respiration
Respiration is an exothermic reaction
Whats metabolism
Metabolism is the sum of all the chemical reactions the takes place in the body
What’s urea
Urea is a waste product when protein is broken down
Whats fermentation
Anaerobic respiration in yeast
What’s are the products of anaerobic respiration
Ethanol and carbon dioxide
