Cellular Respiration. The term cellular respiration refers to the biochemical pathway by which cells release energy from the chemical bonds of food molecules and provide that energy for the essential processes of life.All living cells must carry out cellular respiration.t can be aerobic respiration in the presence of oxygen or anaerobic respiration. Prokaryotic cells carry out cellular respiration within the cytoplasm or on the inner surfaces of the cells. More emphasis here will be placed on eukaryotic cells where the mitochondria are the site of most of the reactions.
The National Heart, Lung and Blood Institute notes that while inactive, overweight women usually need 1,000 to 1,200 calories daily for weight loss, active, overweight women and women weighing more than 164 pounds usually require 1,200 to 1,600 calories each day.
As a rough guide, a small female doing less than an hour of exercise each day will require just 1400 to 1600 calories each day, while an average male will need just 1800 to 2200 calories per day. Based on this for sustainable weight loss, women will generally respond well to any dietary regimen based on 1200 to 1400 calories and a male 1600 to 1800 calories per day. While this may sound a lot of calories, the truth is once you keep a strict log of the calories you consume, you will see how easy it is to eat more than this on an average day.
