Enzymes, Biomolecules, Photo/CR

Enzymes are responsible for ​ (a)   and they are considered a ​ (b)  

• Speeding up reactions
• catalyst
• slowing down reactions
• carbohydrate
• lipid
• nucleic acid

What happens when enzymes are heated to a high temperature?

• The enzymes die.

• The shapes of the enzyme are altered (denature)

• The enzymes' amino acid sequence changes.

• The enzymes remain the same

An enzyme speeds up a reaction by

• lowering the activation energy.

• raising the activation energy.

• releasing energy.

• absorbing energy.

What is the process (equation) for photosynthesis?

• 6CO₂ + C₆H₁₂O₆ --> 6H₂O + 6O₂

• 6CO₂ + C₆H₁₂O₆ --> 6H₂O + Energy

• 6H₂O + 6CO₂ --> C₆H₁₂O₆ + 6O₂

• 6O₂ + C₆H₁₂O₆ --> 6CO₂ + 6H₂O
