This blog will cover and explain the specification for Edexcel triple science course 2013 for biology. Hope it helps :)
Haha I'm gald!
thank you so much!
will the product be a simple sugar?
Yes, because amylase breaks down starch into the sugar maltose, which is a simple sugar.
Yes that's right, thanks for helping :)
What colour will the iodine turn when it stops being blue/black??

Doesnt it have to change to Blue Black, because it is Iodine??? Red to Blue Black, it said in like 2.7 of your blog???
It will start off as blue/black as there is starch in the solution however you will know when there is no more starch as the iodine in the solution will turn a red/brown colour

Is it fine if I wrote Enzyme catalase ,which breaks hydrogen peroxide into water and hydrogen Catalase in found in potatoes , therefore putting potato chips into preoxide will produce O2 .the rate of reaction is therefore proportional to the volume of 02 given off. The changing in temperature will alter the volume
How enzyme activity can be affected by changes in temperature
Can someone help me please
