Unit 5 P1 Animal Cell Nucleus- the nucleus in an animal cell controls every activity that happens within the cell Cell membrane- The cell membrane is a thin semi-permeable membrane that surrounds the cytoplasm of a cell. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell‚ while keeping other substances out. It also serves as a base of attachment for the cytoskeleton in some organisms and the cell wall in others. Thus the cell membrane

proteins‚ lipids‚ and nucleic acids. Each of these macromolecules (polymers) are made of smaller subunits (monomers). The bonds between these subunits are formed by dehydration synthesis. This process requires energy; a molecule of water is removed (dehydration) and a covalent bond is formed between the subunits . Breaking this bond is called hydrolysis; it requires the addition of a water molecule and releases energy. Each class of these macromolecules has different structures and properties. For example

Brittney Humphries. Title: Testing for the Presence of Starches‚ and Proteins Purpose: To test for the presence of starches and protein macromolecules‚ to introduce the concept of variations in chemical compounds. Hypothesis: If biuret is blue after a test for protein‚ then it is a negative result because biuret reagent is blue to begin with. If a solution is pinkish purple‚ or purple‚ then the test for protein is positive. The test solution for starches is yellowish brown. If any substance

The Nucleus: In the kingdom the nucleus is the king. The nucleus is a membrane-bound organelle found in the center of the cell that contains all of the genetic information‚ and DNA and controls the rest of the cell. To the kingdom the nucleus is the king because of how he controls the kingdom and is responsible for the wealth of the town through his actions. Additionally not all cells have a nucleus. Just as not all kingdoms have a king. The Nuclear Envelope: The nuclear envelope is similar to

GAME. LYSOSOMES=DEFENSIVE LINE LYSOSOMES CONTAIN ENZYMES THAT BREAK DOWN LARGE MOLECULES TO BE USED BY THE CELL. A CELL CONTAINS A VARIETY OF LYSOSOMES THAT CONTAIN DIFFERENT ENZYMES THAT SPECIFIC MACROMOLECULE. THE LYSOSOMES PROVIDE AN ACIDIC ENVIRONMENT SO ENZYMES CAN BREAK DOWN LARGE MACROMOLECULES WITHOUT DISTURBING THE FUNCTIONS OF OTHER MOLECULES IMPORTANT TO THE CELL. THE DEFENSIVE LINE BREAKS DOWN THE OFFENSE ON THE OTHER TEAM AND CREATE A SAFE ENVIRONMENT FOR THE QUARTERBACK‚ WHO IS IMPORTANT

BIOL 140 Lab—The Chemical Composition of Cells Name ____________________________ I) Introduction All cells contain four major types of macromolecules: carbohydrates‚ lipids‚ nucleic acids‚ and proteins. In today’s lab‚ we will be studying three of the four-proteins‚ carbohydrates and lipids. Various chemical tests can be used to detect the presence of each of these molecules. Most of the tests involve a color change visible to the eye. If a color change is observed‚ the test is considered positive

THE CHEMISTRY OF ORGANIC MOLECULES I. MACROMOLECULES-large molecules that are composed of smaller molecules and atoms that are bonded together. These are among the largest of all chemical molecules. A. Polymers-the largest of the macromolecules. These are composed of numerous‚ small identical subunits known as Monomers. There are 4 major polymers that are important for living organisms. These polymers are; carbohydrates‚ lipids‚ proteins and nucleic acids. B. Polymers

them. The Golgi apparatus is a stack of half a dozen or so flattened‚ membranous sacs called cisternae. It basically looks like a stack of pancakes. The main function of the Golgi is to process‚ package‚ and deliver macromolecules‚ such as proteins and lipids. These macromolecules are sent to the Golgi after being built in the ER‚ which is the Endoplasmic reticulum‚ enclosed in tiny vesicles composed of membranes from the ER‚ so it can inspect them for flaws and discard any extra materials added
