AQA BIOLOGY UNIT 1 21st MAY 2014

You had to give two features.

Many mitochondria

Micro villi

= 2 marks

yes but then you had to explain why they are good adaptions for absorption

MicrovilIi increases surface area

Mitochondria creates atp for active transport

yeah i put increased surface area for the microvilli but for mitochondria i said it uses glucose in respiration so lowers the glucose concentration of the cell so increases diffusion into cell. its a different point to the active transport point but is it not still correct?

Glucose doesn't enter via diffusion ever it's always active transport so I don't think diffusion will get credit. I think you had to say mitochondria produces ATP for active transport

Hello! If you still have it, could I possibly have the Unit 1 mark scheme for Biology please??
Thank you
