Question

7:17 PM Mon Sep 24 colorstate.grtep.com HomeAccount Internal Messages Print Help Logout Search: CHAPTER 10 In chapter 10 we discussed the biochemical standard free energy and mentioned how this is a reference" point for standard free energy. This is similar to sea-level being used as a reference point for measuring elevation. In other words, standard conditions are an agreed upon "starting point" to measure free energy changes to "normalize" all of the data. How could we extend this analogy (measuring elevation from sea-level) to actual free energy changes? Words:0 SUBMIT CHAPTER 11 In chapter 11 we went over two metabolic pathways and two mitochondrial shuttles. There is a lot of details in each of these topics. FOR GLYCOLYSIS name three "key points" for this portion of the material.

Explanation / Answer

Sea level varies a quite lot on several scales of time and space.This is because thesea is in constant motion affected by tides, winds,atmospheric pressure and so on.Height above the sea level is the "ELEVATION" (on the ground) People have been keeping the track on sea level from about 200 years.Recently, the tide gauges which are water levelrecorders anchored to some structure along the coastline.The tide gauge is a large pipe inserted into the sea,which has a float inside the moves up and down as the water level changes.These gauge records the changes and helps in measuring the sea level.The Global TeleCommunication system is preferred as means of transmitting the tide gauge data from their source to the concerned data centres.

To measure the distance to the sea surface, the satellites send the microwave pulse to the ocean's surface and record the time it takes a return. A microwave radiometer corrects any delay that can be caused by the water vapour in the atmosphere. Mean sea level is calculated from long series of hourly observations.The simplest way is to take arithmetic average.The average of both the high and low water levels is called mean tide level.It is close but not equal to mean sea level.
