HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!

I Had a Practice Practical in Biology

My Practical procedure was Cutting off some cabbage leaf and heat it up with a sucrose solution with an enzyme in.


Could You please tell me what Knowledge I was lacking and the correct answers, as I couldn't answer the question
This is because this is the first time where I have no clue as what should I right.
Good It was a practice Practical, not the real Biology Qualatative

Any Help would be appreciated

1. You heat it up because this will increase the energy levels of the enzyme and substrates (sucrose). This will increase the rate of reaction so that perhaps your experiment occurs quicker. More heat is higher rate of reaction.

2. My guess is this: The cells are different sizes because it means they can unifromly structure the cabbage leaf. this means that the cabbage can be made of more cells. this means there is a higher rate of photosynthesis because there are more cells to photosynthesise (Im not sure this is quite relevant though)

3. If you increase - higher rate of reaction since there is lots of substrate but enzyme concentration becomes limiting factor as they are working at their highest rate and there are sucrose molecules still waiting to bind to the enzyme active site.

Hope this helps you , Im guessing you needed help

Thank You very Much

Sorry I am actually not quite dumb
so could you explain the question 3 in a more dumber way so that I can understand

Thank You

So change the sucrose soltion would mean:
1. Add more sucrose in the solution - this means there are more sucrose molecules in the liquid it dissolves in
2. reduces the sucrose concentration in the solution - have less molecules dissolved in the liquid

Picture it like an orange cordial drink. If you add more orange juice and make it more concentrated (higher concentration of juice) then there will be more orange juice in the water

If you add less orange juice, there will be a lower concentration of orange juice in the water as you have added less

You seem really clever
did you do Biology AS
If so have you got any tips

No I'm doing OCR
