    ME TOO- this is kinda what i know but im really bad at explaining let me know if ive missed anything

    Beer is made from barley seeds which is starch( it needs to broken down into smaller molecule).
    in order to be broken down the barley seeds need to produce amalyse( which is the enzyme that breaks down starch).
    amylase is produced by germinating the barley seeds- by soaking in water and leaving in a malt house.
    then the amylase produced breaks down the starch into glucose. the yeast then anaerobically respires and breaks down the maltose into ethanol and co2.

    ethanoll is alcohol which is beer
    Thanks

    Points you missed:-
    -Seeds are killed and dried to make malt
    -Hops are added for taste
    -Beer is centrifuged, filtered and sometimes pasteurised
    -Put into casks or barrels

    Malt is made cause starch is broken down into maltose, it's dried for some magical reason which I'm sure is cool. It does make beer

    Let me put like this;
    Light , CO2, Temperature are the main limiting factors that matter in the exams

    When light increases the rate of photosynthesis increase until a certain point when photosynthesis evens off
    This is because the 2 other factors; amount CO2 or the temperature will not support (not sure if that's a good word) a higher rate of photosynthesis. The same is true for any of the 3 factors where one factor no longer supports the a higher rate of photosynthesis and has now become the limiting factor

    Hope that helps
