Understanding

• Metabolic pathways consist what two types of enzyme catalysed reactions?
• What do enzymes do in a chemical reactions?
• What are the two types of enzyme inhibitors?
• What can metabolic pathways be controlled by?

Metabolic Pathways

• What is metabolism defined as?
• Most chemical changes in a cell result from? (No specific or technical word)
• Metabolic pathways allow for a greater level of what and why?
• Metabolic pathways are typically organised into?
• What is biogeochemical cycle?
• Give examples of chains?
• Give examples of cycles?

Types of Metabolic Pathways

Activation Energy

• Every chemical reaction requires a certain amount of what?
• What do enzymes do to a biochemical reaction and how does it do it?
• When an enzyme binds to a substrate, how does it impact the bonds of the substrate?
• What does that do with the energy level and what would that mean as a result of the change in energy?
