Answer 1

PROTEIN: A large molecule composed of one or more chains of amino acids in a specific order determined by the base sequence of nucleotides in the DNA coding for the protein.

Proteins are required for the structure, function, and regulation of the body's cells, tissues, and organs. Each protein has unique functions. Proteins are essential components of muscles, skin, bones and the body as a whole.

Examples of proteins include whole classes of important molecules, among them enzymes, hormones, and antibodies.

Protein is one of the three types of nutrients used as energy sources by the body, the other two being carbohydrate and fat. Proteins and carbohydrates each provide 4 calories of energy per gram, while fats produce 9 calories per gram.

ENZYME: A protein (or protein-based molecule) that speeds up a chemical reaction in a living organism. An enzyme acts as catalyst for specific chemical reactions, converting a specific set of reactants (called substrates) into specific products. Without enzymes, life as we know it would not exist.

MINERALS: the chemical elements required by living organisms, other than the four elements carbon, hydrogen, nitrogen, and oxygen which are present in common organic molecules which are used as cofactors in metabolism. Examples are Na+ (sodium), K+ (potassium), Mg+ (magnesium), and Fe+ (iron)..

BLOOD: The familiar red fluid in the body that contains white and red blood cells, platelets, proteins, and other elements including vitamins, minerals, enzymes and hormones. The blood is transported throughout the body by the circulatory system. Blood functions in two directions: arterial and venous. Arterial blood is the means by which oxygen and nutrients are transported to tissues while venous blood is the means by which carbon dioxide and metabolic by-products are transported to the lungs and kidneys, respectively, for removal from the body.

VITAMINS: nutrients that are organic compounds required in tiny amounts for essential metabolic reactions in a living organism. The term vitamin does not include other essential nutrients such as dietary minerals, essential fatty acids, or essential amino acids, nor does it encompass the large number of other nutrients that promote health but that are not essential for life. They act as catalysts and substrates in metabolism, that is, like enzymes and minerals, they are not consumed.

HORMONE: A chemical substance produced in the body that controls and regulates the activity of certain cells or organs.

Many hormones are secreted by specialized glands such as the thyroid gland. Hormones are essential for every activity of daily living, including the processes of digestion, metabolism, growth, reproduction, and mood control. Many hormones, such as the neurotransmitters, are active in more than one physical process. Examples of hormones include aldosterone, antidiuretic hormone(ADH), cortisol, erythropoietin, estrogen, human chorionic gonadotropin (hCG), parathormone, progesterone, and testosterone.

Answer 2

I'm not a vegan, and would never become one, but I'd suggest you go to a forum for vegans. That would probably help on a daily basis. They usually have recipes as well. I really hope you know everything about vitamins, etc. so as not to have any deficiency (right word?) Also, if you eat well at each meal, and maybe have a snack at 10 and one at 4 or 5, you shouldn't have cravings. I think you should eat large quantities so as to fill your stomach and not feel hungry. ps: I've just had a look at the vegan pyramid. Be careful with nuts. My uncle (although not a vegan) used to eat nuts all the time during the day (he works in markets, and has to stand in the cold all day). Well, he went to the doctor for a check-up, and the doctor actually told him to stop eating nuts because he had too much of something in his body, and it was quite dangerous. Who would have thought that of nuts? Remember that too much of everything can be dangerous. Regularly checks different sources for your info.

Well, blood is actually an organ that consists of several different kinds of cells.

All of the other things in your list are different kinds of molecules that make up and are found in all cells and tissues. Each one of these will have a specific definition or description that you should be able to find in the glossary of your textbook or within the section that discusses each one.
