Metabolic Pathways and Enzymes Cellular reactions are usually part of a metabolic pathway, a series of linked reactions Illustrated as follows: E 1 E 2.
Energy – the ability to do work or bring about a change Cells need energy to maintain their organization Cells need energy to carry out reactions used.
Enzymes: “Helper” Protein molecules Enzymes Catalysts for biological reactions Most are proteins Lower the activation energy Increase the rate.
Enzymes Lab 5. Enzymes Reaction characteristics – Enzymes are catalysts: substances that speed up or facilitate a chemical reaction by LOWERING the activation.
Chapter 4 How Cells Work. Energy Energy is central to life –Universal relationship between energy and work Ultimate energy source = SUN –Plants transform.
