What are the two different cells?
Plant and animal Cells
1 of 31
Name 3 parts you can find in animal and plant cells?
Nucleus, proteins, enzymes, respiration and photosynthesis
2 of 31
What begins with C and is in a plant and animal cell?
Cytoplasm
3 of 31
Name the 3 extra things that animal cells do not have?
Cell wall, Vacuole, Chloroplasts
4 of 31
What are single celled microorganisms?
Yeast
5 of 31
What does bacteria cells have? (Name 3)
Cell membrane, cell wall, cytoplasm and DNA molecule
6 of 31
What would happen without enzymes?
Chemical Reactions taking place inside the cells would run dead slowly
7 of 31
What are enzymes?
a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction
8 of 31
What happens when enzymes involve?
They either split apart or join together
9 of 31
Why has enzymes got a 'lock and key' model?
Because the substrate joins on to the enzyme just like a key
10 of 31
Why do enzymes need to be a specific constant temperature?
To work at their opitmum
11 of 31
What is Aerobic respiration?
the release of energy from glucose or another organic substrate in the presence of Oxygen.
12 of 31
What is the energy released used by respiration?
Used to power some of the chemical reactions
13 of 31
What does Aerobic mean?
With Oxygen
14 of 31
What is more released in Aerobic Respiration then Anaerobic Respiration?
Mole energy per glucose molecule
15 of 31
What is the word equation for Aerobic Respiration?
Glucose + Oxygen = Carbon dioxide + Water
16 of 31
What is the symbol equation for Aerobic Respiration?
C6 H12 O6 + 6O2 = 6CO2 + 6H2O
17 of 31
What begins with O and Aerobic Respiration doesn't use this?
Oxygen
18 of 31
Where does Aerobic respiration take place?
Human Cells and Plant Cells
19 of 31
What is the word equation for Anaerobic Respiration which can produce Lactic Acid?
Glucose = Lactic Acid (+Energy Released)
20 of 31
What is the word equation for Anaerobic Respiration which can produce Ethanol and Carbon Dioxide?
Glucose = Ethanol + Carbon Dioxide (+Energy Released)
21 of 31
What is the word equation for oxygen which is produced as a waste product of photosynthesis?
Carbon Dioxide + Water = (Light Energy) = glucose + oxygen
22 of 31
What is the symbol equation for oxygen which is produced as a waste product of photosynthesis?
6CO2 + 6H2O = (Light Energy) = C6 H12 O6 + 6O2
23 of 31
What 3 ways do plants use glucose?
Respiration, chemicals for growth and stored as startch
24 of 31
What are the 3 factors that Rate of photosynthesis?
Amount if light, Amount of CO2 and temperature
25 of 31
What are the 3 important graph for the rate of photosynthesis called?
Not enough light slows down the rate of Photosynthesis, Too little carbon dioxide also slows it down and The temperature has to be just right
26 of 31
What is Transect?
A way of investigating how something changes across an area
27 of 31
What are the 3 things that will help you collect data?
Light Meter, Quadrat, and Identification key
28 of 31
What is Diffusion?
The passive overall movement of particles from a region of their higher concentration to a region of their lower concentration
29 of 31
What is Osmosis?
The overall movement of water from a Dilute to a more concentrated solution through a partially permeable
30 of 31
What is Active transport?
The overall movement of chemicals across a cell membrane from a region of lower concentration to a region of higher concentration using energy released by respiration
