AQA GCSE Biology : bioenergetics
Oxygen and glucose
how does water enter a plant ?
Roor hair cells
What is an endothermic response?
A response that takes in energy from the surroundings
what are uses for glucose in plants ?
- for respiratory
- to make starch
- to make cellulose
In the specified practical to analyze how mild intensity influences photosynthesis, what might
you anticipate to manifest as the space between the lamp and the plant is accelerated?
Less oxygen is produced
The realistic entails the dimension of oxygen bubbles in the water. Through which a part of
the plant is oxygen launched?
The stomata
If a 6 cm bubble of oxygen is acquired over 5 mins, what is the charge of response?
1.2 cm/minute
The fee of reaction is 1.2 cm/minute (because 6/5 = 1.2).
What are the proscribing factors of photosynthesis ?
- light
- chlorophyll
- carbon dioxide
Which of the subsequent describes a plant that has been attacked by the tobacco mosaic
virus?
Mottled mosaic of yellow patches on its leaves. This is because the virus destroys the
chloroplasts that provide vegetation their green colour.
, As the concentration of CO2 will increase, the rate of photosynthesis can even growth until it
reaches a height and then plateaus. At this top, the CO2 is stated to be at:
surest awareness
What happens to the fee of photosynthesis when the temperature is accelerated?
The fee of photosynthesis will increase with temperature up to an premiere. As the
temperature maintains to rise, the rate of photosynthesis starts offevolved to fall
unexpectedly
Why does the rate of photosynthesis begin to lower because the temperature increases
above optimal?
The enzymes controlling photosynthesis are denatured
what is breathing ?
Transfer of power from glucose and it takes place in each cellular.
Which tactics require electricity from respiration ?
- Muscle contraction
- Building proteins from amino acids
- Moving minerals into cells in plant life
what type of response is respiration ?
Exothermic
what's the phrase equation for cardio respiratory ?
Glucose + oxygen → carbon dioxide + water (+ energy)
Does aerobic respiratory switch greater strength than anaerobic breathing ?
YES
Aerobic respiration transfers lots more strength according to glucose molecule than
anaerobic respiration (38 kJ in comparison with 2 kJ).
What is produced when flora and fungi respire anaerobically ?
Ethanol + CO2
what's the storage molecule for glucose
glycogen
