EDUCAKE Flashcards
Where does photosynthesis occur?
Chloroplast
True or false? Ethanol is an example of a biofuel.
true
What type of respiration occurs when oxygen is in short supply?
Anaerobic
Name the microorganism that is used to make wine from grape juice.
yeast
What is the missing word? Aerobic respiration is respiration which uses glucose and __________.
oxygen
The build up of which acid causes fatigue in vigorously exercising muscle?
lactic acid
Photosynthesis requires energy. What gives energy to a plant?
sun
What word is used to describe respiration which “uses oxygen”?
aerobic
Ethanol can be produced using yeast. What is this process called?
fermentation
Which gas is produced as a waste product of aerobic respiration? Give the name, not the symbol.
carbon dioxide
Photosynthesis is a chemical reaction in which the energy stored in the sun is transferred to molecules of __________. What completes the sentence?
sugar called glucose
During photosynthesis, what does carbon dioxide react with to make carbohydrate?
water
True or false? Respiration releases energy.
true
When plants respire, what gas is released into the atmosphere?
carbon dioxide
What sugar is formed in photosynthesis?
glucose
What waste chemical is produced in anaerobic respiration in animals?
lactic acid
What is the advantage of anaerobic respiration for animals?
It releases quick bursts of energy without needing a sudden increase in oxygen supply, which can help animals sprint away from a predator.”
In aerobic respiration, glucose and oxygen are used up and carbon dioxide, water and __________ are released. What one word completes the sentence?
energy
The rate of photosynthesis is controlled by light intensity, availability of carbon dioxide and which other factor?
water
Where does aerobic respiration mainly take place?
mitochondria
What substance, apart from yeast, is needed to make ethanol by fermentation?
glucose
What is the chemical in leaves that absorbs light?
chlorophyll
True or false? All living things respire all the time.
true
True or false? Plants only respire at night.
false
