Ap Biology Unit 9 Study Guide

Carbohydrates, proteins and lipids are known as macronutrients as the body needs masses of these nutrient components in order to carry out the bodies’ essential functions.

What is the function of ribosomes? What are their two components? Ribosomes are the cellular components that carry out protein synthesis. Their two components are a large subunit and a small subunit.

The digestive system absorbs the minerals and nutrients from the foods that have been eaten. The break down of food beings in the mouth, where the

Inside our body there is a powerful muscular pump, which is known as the one of the main organs in the human body. This hollow, cone shaped, pump lies slightly left within the center of the chest called our heart. The heart is made up of different structures and actions in order for it to work, combined with a network of blood vessels form what we know as the cardiovascular system.

B7 (Biotin): Depression, lack of intestinal absorption, inflamed bowel syndrome, skin irritation, hair loss, poor muscle control, seizures, development delayed

Surface Tension: The measure of how difficult it is to stretch or break the surface of a liquid.

3. State the name and structure of the functional group for each type of biologically

a. Proteins- macromolecules made of amino acids. Proteins have many functions in the body. Some sources of proteins are whole-grain cereals, dark breads,rice, beans, and meat.

In eukaryotes, stored primarily in the cell nucleus. A nucleic acid using deoxyribose rather than ribose.

Digestion is a process in which insoluble food is broken down into particles which are made into soluble particles enough to be absorbed and to be used by the body and into the bloodstream. These soluble particles are major macronutrients made up of protein, carbohydrates and fats which are needed for essential maintenance for the functioning of the human body. Nutrients are found in foods- proteins are found in red meat/poultry; sources of carbohydrates include

Carbs are found in in grains, fruits and vegetables such as wheat, corn, rice and cassava.

The digestive system are organs converting food into energy and basic nutrients to feed the entire body.

The digestive and excretory systems help the body with the wonderful task of food. The digestive system is composed of the stomach, mouth, liver, pancreas, and the large and small intestine. It digests food and provides the

Carbohydrate is a nutrient essential for energy production and the prevention of ketosis, a state where the production of ketones exceeds metabolism. Protein is a nutrient essential for its components, amino acids. Fat is a nutrient which provides insulation, protection and energy for the body.

Cells are some of the smallest organisms around. All living things consist of cells, and yet they are invisible to the naked eye. Cells are the basic structural and functional units of life. Cells are made up of many different parts which allow them to function properly.
