Energy And Nutrition

Energy and Nutrition

Cells release aptitude through an exergonic transit called cellular respiration. Aerobic cellular respiration is a chemical process that uses oxygen to convert the chemical brawn stored in victuals molecules into chemical energy that the cell can use, called ATP. Based on what I know about macromolecules ( motorcarbohydrates, fats, and protein) and energy, I think that my normal, day by day dietary consumption is healthy on some days, bargonly most days my diet is unhealthy. On a prone day, such as yesterday, I consumed approximately 1,500 calories, or kilocalories, which is the energy required to raise the temperature of 1 kg of water by 1 degree Celsius. My day started out with bacon, egg, and cheeseflower on a whole wheat bagel. For lunch I had pepperoni and cheese on a whole wheat bagel and then for supper I had homemade flush stew over rice. The beef stew contained carrots, potatoes, green beans, onions, mushrooms, and of course beef. For beverages, throughout the day, I drank more often than not water and had 1 glass of grape juice. I would tell apart that that day my diet wasnt too unhealthy. My problem isnt necessarily what I eat, but how overmuch I eat. I always go for seconds, and my fat cells love it! So, why do we need food, what is it made of, and what is our body doing with it?

We need food, in much the same way, as a car needs fuel. The car gets its energy from the fuel and we get our energy from calories that are contained in the many foods we eat. Many people, when they think of psyche using energy they adjudge a picture in their mind of someone who is running, walking, or doing some physical work; but, the cells in our bodies are constantly using energy every second. Even when sleeping, our patrol wagon keep beeping and our lungs continue to exchange air. Not only do the foods we eat contain the fuels to keep our bodies running, but they also have many nutrients that help keep our bodies healthy.
