Problem 11E

Why do some electrochemical cells employ inert electrodes such as platinum?

Step-by-Step Solution:
Step 1 of 3

Chapter 6: How cells harvest chemical energy  You can transfer phosphate from ATP to a molecule to give it energy  Most of energy that is made is lost and no longer available Cellular respiration  Energy for living organisms comes from photosynthesis and cellular respiration  Energy ultimately comes from the sun o Only about 10% of this energy is actually used… the rest of it goes into the environment  Glucose is broken down to carbon dioxide and water in cellular respiration  The cell captures some of the energy that is released to make ATP  Takes place in the mitochondria of eukaryotic cells  Cellular respiration is not breathing!!!  An exergonic process that transfers energy from glucose bonds to ATP o This is not done in just one reaction…. It takes many reactions and step by step processes  The number of ATP molecules from each glucose varies  About 34% of the energy originally stored in glucose is captured o Other organic molecules besides glucose can be used  Equation for cellular respiration is: glucose + oxygen = 6 molecules of carbon dioxide + 6 molecules of water + ATP + heat  Is the CONTROLLED breakdown of organic molecules Photosynthesis  Chloroplasts capture energy in photosynthesis  Atoms of carbon dioxide and water are rearranged  As a result, carbohydrates and oxygen are produced Aerobic harvesting of energy  the energy for life is contained in the arrangemen
