| Question | Answer |
| What is a Eukaryotic Cell? | A Eukaryotic cell is a cell which does contain a nucleus. |
| What parts of a cell do plants have that animal cells do not? | Vacuole, Chloroplasts, Cell Wall. |
| What is the role of a ribosome? | Where proteins are made in the cell. |
| How do Prokaryotic cells reproduce? (Cells without a nucleus) | Binary Fission. |
| What is the equation to find the Magnification of a Microscope? | M=I/A Magnification= Image size/ Actual size |
| What does a Stent do to a blood vessel? | A stent opens the passageway of a blood vessel in order to keep blood flowing through it. |
| What is photosynthesis? | Photosynthesis is the reaction within a plant where carbon dioxide diffuses into the plant and oxygen is given out from the plant. |
| What is an Enzyme? | An enzyme is a chemical catalyst that speeds up the reaction of breaking down foods and substances. |
| What is the role of a Mitochondrion/a? | Produces energy within the cell using Aerobic Respiration |
| What is the role of a cell wall? | To keep the shape and structure of a plant cell. |
| How can an enzyme become denatured? | If the body becomes too hot the enzyme can denature and lose its shape but also if the pH is not correct, it will also denature and die. |
| What is the optimum temperature for enzymes? | 37 Degrees Celsius |
| Name 3 Enzymes and the foods which they act upon | Carbohydrase=Carbohydrates Protease-Proteins Lipase-Lipids (Fats and oils) |
| Name the products made from these 3 Enzymes | Carbohydrase=Sugars and Glucose Protease=Amino Acids Lipase=Glycerol and Fatty Acids |
| What is the Lock and Key theory? | The lock and key is a theory which states that each enzyme has a lock-like active site that only suits a certainly shaped substrate which means specific enzymes break down specific substrates. |
| What is the Collision Theory? | The Collision Theory states that the faster substrates react and collide with enzymes, the faster the rate of reaction. This means digestion happens faster. |
| State the role of the cell membrane. | The role of the cell membrane is to control what enters and exits its cell. |
| What do chloroplasts do within a plant cell? | Chloroplasts take in light energy and convert it into chemical energy using photosynthesis. |
| What are antibodies and what do they do? | Antibodies are small products of White Blood Cells that cling to pathogens and send out signals to the body so the pathogen can be killed. AN ANTIBODY IS A WAY OF KILLING PATHOGENS THAT WERE PREVIOUSLY IN THE BODY AND NOT NEW. |
| What is Haemoglobin's job in Red Blood Cells? | Haemoglobin transports oxygen around the body. |
| Name 3 adaptations of |
