Worked Solution & Example Answer:A student investigated the effect of enzyme concentration on the mass of product formed in one hour - Edexcel - GCSE Biology - Question 5 - 2018 - Paper 1
Step 1
Complete the graph by plotting points
Answer
First, plot the remaining points on the graph. For the enzyme concentrations of 15, 20, 25, 30, 35, and 40 arbitrary units, the corresponding masses of product are 25, 32, 38, 40, 40 grams respectively. Ensure that each point is accurately placed within half a small square as per the instruction.
Step 2
Draw a line to show the trend
Answer
After plotting all points, draw a line through the points to show the trend of the data. The line should begin to rise steeply as enzyme concentration increases, leveling off around 30 arbitrary units and 40 grams, indicating a point of saturation where additional enzyme concentration does not result in increased product.
