A macromolecule can best be described as an immense molecule‚ made up of thousands of covalently bonded carbon atoms. There are four classifications of macromolecules: carbohydrates‚ lipids‚ proteins‚ and nucleic acids. Each classification performs specific functions that allow cells to grow and survive. Macromolecules can be either split or bonded through dehydration synthesis or hydrolysis. Dehydration synthesis occurs when water is released‚ electrons become shared‚ covalently bonding two

Chapter 5 An Introduction to Carbohydrates Carbohydrate – sugars‚ encompasses the monomers‚ called monosaccharides‚ small polymers called oligosaccharides‚ and large polymers called polysaccharides 5.1 Sugars as Monomers 1. How Monomers Differ a. Monosaccharide – simple sugar‚ monomer i. Carbonyl group serves as a distinguishing feature 1. At end of molecule‚ forms an aldehyde sugar (aldose) 2. In middle of molecule‚ forms a ketone sugar (ketose)

BS801 Genes R Us Questions for study: 1. What functions do transcription and translation carry out‚ and where are they carried out in the cell? Transcription: process of creating an equivalent RNA copy of a sequence of DNA Transcription is the first step leading to gene expression. The stretch of DNA transcribed into an RNA molecule is called a transcription unit and encodes at least one gene. Occurs in nucleus of the cell Translation: Translation is the production of proteins by decoding mRNA produced

Biochemistry: Biological Molecules Pg. 2 – 7 Carbohydrates Pg. 8 – 12 Proteins Pg. 13 – Lipids Carbohydrates. L.O. 1.1 and 1.2 Carbohydrates are sugars and they are the primary source of energy for our vital functions such as breathing and sleeping. There are two types of carbohydrates‚ simple and complicated. Monosaccharides‚ disaccharides and polysaccharides. L. O. 1.2 Carbohydrates are split into different classifications depending on how many molecules they have. Monosaccharide: one sugar

A Description of Cochlear Implants A Cochlear Implant is a specialized hearing device that consists of both a surgically-implanted and external component used to simulate natural hearing. This device is used to treat people with severe and profound hearing loss. The implanted component is placed under the skin‚ behind the patient’s ear‚ and connected to the auditory nerve of the brain. The Cochlear Implants are designed to receive sounds and convert them into electrical signals that bypass

The Earth has a plethora of organisms that live and reproduce all throughout its surface. Depending on what kind of organism‚ they go through some processes that others life-forms do not need to do. However‚ the molecules DNA and RNA‚ which are found in all living creatures‚ work together in a certain process that is crucial to existence: the formation of proteins. Although all species differ from each other in various ways‚ the processes by which proteins are synthesized are the same in all.

SAFAVOV & EDuardo vie (Group 3) OBSERVATIONS & HYPOTHESIS In the lab‚ we observed green plant leaves convert light energy into chemical energy by using photosynthesis. The species of green plant leaves that were used in this experiment were Hedera helix‚ commonly known as English Ivy. These plant leaves have both mitochondria and chloroplasts. The process of photosynthesis takes place in the chloroplasts and aerobic respiration is carried out in the mitochondria‚ these reactions may occur simultaneously
