How are lipids and enzymes different?

• lipids control - enzymes denature proteins
• lipids support cells - enzymes change the cell's pH
• lipids store energy - enzymes act as biological catalysts to speed up reactions
• lipids build structures - enzymes carry substances through the body

Enzymes are capable of increasing the rate of a chemical reaction within a living cell.  Enzymes accomplish this through which of the following means?

• reducing the number of products   
• reducing the activation energy
• increasing the temperature of the cell
• increasing the concentration of reactants

Which of the following is the correct equation for PHOTOSYNTHESIS?

• 6CO₂ + 6H₂O --> 6O₂ + C₆H₁₂O₆
• 6CO₂ + C₆H₁₂O₆ + 6H₂O --> O₂ 
• 6O₂ + 6H₂O --> 6CO₂ + C₆H₁₂O₆
