Paper 3 Qs2~Enzyme

The question is about one of the factors which affect enzyme activity which is TEMPERATURE.
And when we talk about enzymes which can be used in Bio Lab, it is usually refer to AMYLASE which can be prepared by using SALIVA.

Please take note the bullets required in your planning...

Please take note about the variables..
Responding variable: the time taken for starch to hydrolyse (also accepted)
Controlled Variable: ONLY ONE.

Apparatus & Materials: All in one..
**Can use water bath as apparatus.

***Need to produce ONE sentence for Safety measures..


Experiments Setup

You may use this apparatus setup for experiments involving YEAST..A manometer..This apparatus for macronutrients experiment..
This one is for energy value..May include 'wind shield' in a diagram!
Photosynthesis experiment ~ whatever manipulated variables are...

Last minute preparation for Bio 2~Diagrams

Watch out for this kind of Diagram. You should be able to identify all the structures, hormone involved..This cross section of DICOT stem...and the longitudinal !!
The secondary growth ~ Watch out the primaries and the secondaries !!
The respiratory structures..The drawing and labelling...
The alveolus..
