Based on the graph, what is the optimal temperature for this enzyme? 

• 15^oC

• 40^oC

• 30^oC

• 35^oC

Answer explanation

Based on the graph, the optimal temperature for this enzyme is 30°C as it shows the highest level of enzyme activity.

What is the purpose  of an enzyme?

• give permission for the reaction

• raise activation energy

• speed up reactions by lowering the activation energy required

• control how many reactions occur

Answer explanation

Enzymes speed up reactions by lowering the activation energy required, making the reaction occur more quickly without being consumed in the process.

Which of the following conclusions can be drawn from this graph?

• The optimum pH of the enzyme is 6.6.
  

• The optimum pH of the enzyme is 5.8
  

• The enzyme’s activity increases as pH increases 5.0 to 9.0
  

• The enzyme’s activity is greater around pH of 8.0 .
  

Answer explanation

The correct conclusion is that the optimum pH of the enzyme is 6.6, as indicated by the highest enzyme activity on the graph.

Diatoms are one of the most common types of phytoplankton in marine habitats. Like plants, diatoms contain chlorophyll and produce glucose from which of the following?

• O₂ and ATP

• CO₂ and O₂

• ATP and H₂O

• CO₂ and H₂O

Answer explanation

Diatoms, like plants, produce glucose from CO2 and H2O through the process of photosynthesis.
