What is a Eukaryotic cell?
A cell which does not have a nucleus.
A single celled organism, like bacteria.
A cell which contains a nucleus, like an animal or plant cell.
A type of cell that can only be found in the human body.
Do all bacteria cells have a/multiple flagellum?
No bacteria cells do not have to have any flagella.
Yes but bacteria can only have a single flagellum.
Yes and bacteria always have more than one flagella.
Yes, and bacteria can have any number of flagella.
Does bacteria have DNA?
No, only plant and animal cells have DNA.
Yes, within a nucleus.
No, bacteria are too small to contain DNA.
Yes, in the forms of loops of chromosomal DNA, and plasmids.
What does a plant cell typically contain?
A cell membrane, cell wall, vacuole, nucleus, mitochondria, chloroplasts, ribosomes and cytoplasm.
A cell membrane, cytoplasm, rybosomes, mitochondria and a nucleus.
A cell membrane, cell wall, plasmid DNA, chromosomal DNA and flagella.
Only a nucleus and chloroplasts.
What is the reaction that takes place during photosynthesis?
Carbon dioxide + Oxygen --> Glucose + Water.
Glucose + Oxygen --> Carbon Dioxide + Water.
Carbon dioxide + Water --> Glucose + Oxygen.
Lactic acid --> Glucose.
Is photosyntheis and endothermic or exothermic reaction?
Exothermic.
Endothermic.
What is the balanced symbol equation of aerobic respiration?
C6H6O6 + 6O6 --> 6CO6 + 6H6O
C6H12O6 + 6O2 --> 6CO2 + 6H2O
6CO2 + 6H2O --> C6H12O6 + 6O2
C6H12O6 --> 2C2H6O +2CO2
What is the difference between aerobic and anaerobic respiration?
Aerobic respiration uses oxygen, whereas anaerobic respiration does not use oxygen.
Aerobic respiration only takes place in humans, and anaerobic respiration takes place in plants and fungi.
Aerobic respiration is the action of breathing, however anaerobic respiration is the reaction that produces energy.
Aerobic respiration produces less energy than anaerobic respiration
How much ATP does aerobic and anaerobic respiration produce?
Aerobic produces 32 molecules of ATP, anaerobic produces 2 molecules of ATP.
Aerobic produces 2 molecules of ATP, anaerobic produces 30 molecules of ATP.
Both types produce 30 molecules of ATP.
Aerobic produces 30 molecules of ATP, anaerobic produces 28.
What is anaerobic respiration in plants and fungi?
glucose --> lactic acid + carbon dioxide.
glucose --> lactic acid.
glucose + oxygen --> ethnol.
glucose --> ethnol + carbon dioxide.
How many stages are there in photosynthesis?
There is only one stage.
There are two stages.
There are three stages.
There are four stages.
What are the stages in photosynthesis?
water and carbon dioxide react to make glucose and oxygen.
Energy is used to split carbon dioxide into carbon and oxygen, water bonds with the carbon to create glucose.
Energy is used to split water into oxygen and hydrogen ions. Carbon dioxide then bonds with the hydrogen ions to make glucose.
carbon dioxide is split into carbon and oxygen, then water is split into hydrogen and oxygen. The carbon, hydrogen and some oxygen reacts to produce glucose.
What is the formula for respiration in animals?
glucose --> ethnol + carbon dioxide.
glucose --> oxygen.
glucose --> ethnol.
glucose --> lactic acid.
What are enzymes?
An organelle that produces amino acids.
Instigators of reactions.
Products of all reactions.
Biological catalysts.
What does the 'lock and key' hypothesis suggest?
That locks can only be opened using a key.
That each type of enzyme can only speed up the reactions of a single type of substrate.
That every living organism creates glucose in a slightly different reaction.
That each enzyme is unique to each person.
How are substrates catalysed?
They enter into an engine.
They bond with sugar.
They enter the active site of an enzyme.
They enter the mitochondria.
Can enzymes be reused?
Yes, they can catalyse reactions without being used up.
Yes, they gradually get used up, but can catalyse multiple reactions.
No, once they have catalysed a reaction they become denatured.
No, enzymes are used in reactions to speed them up.
Are enzymes effected by their surroundings?
Yes, only by temperature, and the higher the temperature the faster they catalyse reactions.
Yes, they become denatured if the temperature is too high, or if the PH is optimal.
No, enzymes always work in the same way no matter the conditions.
Yes, all enzymes are affected by an acidic PH.
