What is respiration? MEASUREMENT OF RESPIRATION IN AN AQUEOUSENVIRONMENTIntroductionOxidation of food produces energy and is used up by the cell to do work.Cellular activities are of different kinds such as propagation of nerve impulse,contraction of muscles and secretion of cellular contents and these are all occurring inthe living cells which require energy.Oxidation of food gives energy to animals. Energy, water and carbon dioxide isreleased when food in animals are metabolized using oxygen.Glucose + oxygen-----> carbon dioxide + water + 673 KcalThe rate of animal oxidizing carbohydrates can be determined by the oxygenconsumption or by the rate of carbon dioxide gas production because the amount ofoxygen intake is equal to the amount of carbon dioxide released.Rates of carbon dioxide exchange per unit weight per unit time can be expressas measurement of respiratory rates. The most commonly units milliliters (mL) CO2 pergram per hour and micromoles (4MCO2) per milliliter per hour.

A number of processes take place in living organisms. All these processes require specialized…

When animals oxidize stored fat, they produce metabolic water.Even though the production of metabolic water from stored fatfollows principles of chemical stoichiometry, the net gain of waterthat animals realize from the oxidation of stored fat depends onthe humidity of the atmosphere. Explain why. Does the net gainincrease or decrease as the atmosphere becomes more humid?
When muscle cells are very active during exercise, they use more ATP energy.Explain how this is related to increased breathing rate and depth (taking moreand deeper breaths) both during exercise and for some time after you finishexercising. Be specific about the cellular respiration processes, inputs, andoutputs occurring in the cells that cause your body to respond with a changein breathing.

You are growing human muscles cells in the lab and you are trying to test how wellthe cells survive with decreasing concentrations of oxygen. As part of yourexperiment, you are measuring the rate of glucose use, the rate of mitochondrial ATPproduction and the pH of the solution surrounding the cells. As the concentration ofoxygen becomes lower änd lower, what changes might you expect to observe inthese cells?A. The rate of glucose use would increase, the rate of mitochondrial ATP productionwould decrease, and the pH of the solution would decrease (become more acidic).B. The rate of glucose use would decrease, the rate of mitochondrial ATP productionwould decrease, and the pH of the solution would increase (become more basic).C.
