?
What's the function of the nucleus?
It contains all of the genetic material of the cell, and controls all of the reaction for that cell.
1 of 40
What is the function of the cytoplasm?
It is where all of the chemical reactions take place.
2 of 40
What is the function of the cell membrane?
It controls what goes in and out of the cell.
3 of 40
What is the function of the ribosomes?
For proteinsynthesis.
4 of 40
What is the function of the mitochondria?
It is the site of respiration and is where energy is produced in the cell (ATP).
5 of 40
Where in the mitochondria does respiration take place?
In the cristae.
6 of 40
Where in the body would you find lots of mitochondria?
Muscle and liver cells.
7 of 40
What is the cell wall made from?
Cellulose.
8 of 40
What is the function of the cell wall?
It gives the cell structure and support.
9 of 40
What is the function of the chloroplasts?
They contain chlorophyll which is used in photosynthesis.
10 of 40
What is the function of the permanent vacuole?
It stores glucose as starch in a plant cell.
11 of 40
Name four uses of bacteria and yeast.
Bread, ethanol, creating cures, sewage treatment and bio-leaching.
12 of 40
Name the ring of DNA in a bacterium?
Plasmid.
13 of 40
What is the function of the flagella?
It is used for the movement of the bacteruim.
14 of 40
Define tissue.
A group of similar cells that work together to form a common function.
15 of 40
Name three specialist tissues in plant.
Xylem, phloem and the mesophyll.
16 of 40
Symbol equation of photosynthesis?
H2O + CO2 --Light--> O2+ C6H12O6
17 of 40
What is the test for starch?
Iodine goes blue/black.
18 of 40
What are the limiting factors of photosynthesis?
Light intensity, carbon dioxide, water and temperature.
19 of 40
What is the function of the cuticle?
It is the top layer of the leaf and makes the leaf water proof so it doesn't loose water.
20 of 40
What are the holes in the bottom layer of the leaf called?
The Stomata, they close at night to stop the leaf loosing water.
21 of 40
What do plants use glucose for?
Respiration, storage and to produce new chemicals.
22 of 40
What is the binding place of the substrate?
The Active Site.
23 of 40
What is the name when the substrate has binded to the enzyme?
Enzyme Substrate Complex.
24 of 40
What is the acid used to break down food in the stomach?
Hydrochloric acid, HCl, pH 2.
25 of 40
Where are enzymes created?
Pancreas.
26 of 40
What enzyme breaks down starch and where is it found? What does it form?
Amylase, found in the small intestine. Glucose and water.
27 of 40
What enzyme is used to break down protein and where is it found? What does it form?
Protease, found in the pancreas. Amino acids.
28 of 40
What enzyme breaks down lipids and where is it found? What does it form?
Lipase, found in the saliva. Breaks down to form fatty acids and glycerol.
29 of 40
What are the functions of bile?
Neutralises stomach acid to produce alkaline conditions for enzymes. It also emulsifies fat.
30 of 40
Where is lipase produced?
In the pancreas and small intestine.
31 of 40
Through what process is ethanol produced?
Fermentation.
32 of 40
Define diffusion?
The movement of molecules from a region of high concentration to a low concentration through a partially permeable membrane until equilibrium is reached.
33 of 40
Name a substance that moves via diffusion?
Oxygen, carbon dioxide or water.
34 of 40
Why glucose get converted to starch?
So it doesn't the water potential of the plant because starch is insoluble.
35 of 40
Define catalyst.
It is a substance that speed up the rate of a reaction without getting used up.
36 of 40
What happens to an enzyme once the temperature goes over 40?
The enzyme denatures because the shape of the active site becomes deformed.
37 of 40
What enzyme changes glucose into fructose?
Isomerase?
38 of 40
What do your muscles convert your glucose into and why?
Glycogen because it is insoluble.
39 of 40
What is produced in anaerobic respiration?
Lactic acid.
