Fill in the blanks: (26 marks)
1. The formula for complete respiration is: _____________________________________
2. The first stage of cellular respiration is called ____________________________

(coenzyme) are also produced during glycolysis.

Graph Assignment: (16 marks)
Temperature and pH have an effect on how fast glycolysis and respiration can occur. Below is a chart
with data concerning an experiment carried out on the rate of glycolysis at various temperatures. Create
one graph with two lines depicting the data provided. Ensure that it show trends (not a line of best fit) by
connecting the dots. The graph must have consistent intervals, titles, and scales for each axes, a overall
legend, and a title for the graph. Then answer the following questions regarding the graph.

1. What would be a good hypothesis for the above data?
2. What is the dependent (responding) variable?
3. What is pyruvic acid?
4. How does knowing the amount of pyruvic acid help determine the rate of glycolysis?
5. Looking at the above data, which organism would one expect to function the best in cold
weather?
6. Based on the graphed data, what conclusions can be made about temperature and the rate of
glycolysis?
