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.
The amount of calories you need varies based on your gender, age and activity level. Womenâs calorie needs are generally less than menâs. Women ages 19 to 30 need about 2,000 to 2,200 daily calories with moderate activity, according to the American Heart Association. Women ages 31 to 50 need about 2,000 daily calories. As you reach age 50, your calorie needs decline to 1,800 daily. To lose belly fat, reduce your calorie intake slightly below these levels, depending on your age. Once you reach your fat loss goal, resume the recommended calorie intake to maintain a healthy body weight.
