1) Metabolism is the process by which your body converts what you eat and drink into energy. During this complex biochemical process, calories in food and beverages are combined with oxygen to release the energy your body needs to function.
Nutrition is the act or process of nourishing or being nourished; specifically : the sum of the processes by which an animal or plant takes in and utilizes food substances.
2) Que is not completely visible in the picture, Please repost.
3) Fiber is important for keeping the digestive tract working smoothly. Since we do notdigest it, the fiber in food passes into the intestine and absorbs water. The undigested fiber creates "bulk" so the muscles in the intestine can push waste out of the body. Eating enough fiber helps prevent constipation.
4) Glycolysis literally means "splitting sugars" and is the process of releasing energy within sugars. In glycolysis, glucose (a six carbon sugar) is split into two molecules of the three-carbon sugar pyruvate.
We have said that animals obtain chemical energy from the food—carbohydrates, fats, and proteins—they eat through reactions defined collectively as catabolism. We can think of catabolism as occurring in three stages. In stage I, carbohydrates, fats, and proteins are broken down into their individual monomer units: carbohydrates into simple sugars, fats into fatty acids and glycerol, and proteins into amino acids. One part of stage I of catabolism is the breakdown of food molecules by hydrolysis reactions into the individual monomer units—which occurs in the mouth, stomach, and small intestine—and is referred to as digestion.
In stage II, these monomer units (or building blocks) are further broken down through different reaction pathways, one of which produces ATP, to form a common end product that can then be used in stage III to produce even more ATP.
5) Firstly, the answer to this question is dependent on species. Secondly, we don’t yet know if there is a precise cellular location for glycolysis to occur or if the enzymes move around based on energetic needs [1] . Thirdly, cytosol is *a* location not *the* location for glycolysis to occur.
For example, in Protozoan Trypanosoma brucei glycolysis occurs in a membrane-bound organelle called glycosome. In some plants and protists, there is substantial evidence that glycolysis also occurs in the mitochondria. Many of the glycolytic enzymes are known to interact with the mitochondrial membranes in Chlamydomonas humans and even yeast.
It is a well known fact that glycolysis in plants occur both in the cytosol and in Plastids. Strangely, we still don’t understand a lot about glycolysis. Since a very generalized, traditional and simplistic version is taught in all introductory biochemistry courses, the prevalent (and inaccurate) answer is cytosol.
As per Chegg policy we are allowed to answer only 4 questions. Please repost the remaing questions again. Thank you.
