what did everyone put for the capsule one? said it needs to be in a capsule because if it was released it would go in the stomach which had a high PH. this wuld denature the enzyme. what did everyone else get?

I put that lipase is not realeased until the duodenum so the contents of the capsual woudnt be released until there because lipase would break down the lipid shell.

would i get any marks for the capsule question?
i put: if it was released before then it would go in the stomach. the PH will be too high and cause the enzyme to denature.
any marks for this?

when it made contact with the bile the capsule would dissolve thus releasing the enzymes

do you know thw question about the superfarms. i believe you were meant to write an advantage and a disadvantage for both traditional farms and super farms. as the question stated to compare them

The question about photosynthesis and respiration in plants where it asked you how much carbon dioxide the plant used in photosynthesis at a certain time, the answer was 33 wasn't it? The net change in carbon dioxide was 22 units but then you had to add on 11 because that is how much it used in respiration. Are you in agreement?

What do you think the grade boundaries will be for this exam. Is it true that they are pushing the grade boundaries up to make it harder for people to get an A* because thats what my teacher was telling out set :/
