Catabolism of Proteins F. Photosynthesis Page 2 BIO 2924 Mr. Smith Unit III Enzymes An enzyme is an organic catalytic agent produced by a living cell. A catalyst is a substance that has the capacity to speed up chemical reactions without itself being altered after the reaction is complete. Characteristics of Enzymes 1. Most enzymes are proteins or proteins combined with other chemical groups‚ and other enzymes (ribozymes) are composed of RNA. Since enzymes are proteins or RNA molecules

How Batteries Work TOPIC: Explanation of how batteries work SPECIFIC PURPOSE: To inform the audience how a battery works on a scientific level THESIS STATEMENT: A battery is essentially a can full of chemicals in which chemical reactions take place to allow for the flow of electrons. Introduction I. Batteries are everywhere. They are in our cell phones‚ our flashlights‚ our cars‚ our laptops. (Attention getter) II. Life as we know it is made possible largely by batteries. III

17 May 2013 Are Protein Shakes Good For You? According to Flex bodybuilding magazine‚ protein shake is the number one selling bodybuilding supplement. Protein powders have been around for years‚ but they are currently gaining popularity and becoming more widely used for their health benefits. In fact protein is one of three food components we require in large quantities. Others are carbohydrates and fats. Your body uses proteins in your diet to build new cells‚ maintain tissues‚ and synthesize

facilitate the successful and secure transfer of IP packets between machines. Ideally‚ TCP/IP is used whenever Windows-based computers communicate over networks. This subject describes the components of the TCP/IP Protocol Suite‚ the protocol architecture‚ which functions TCP/IP performs‚ how addresses are structured and assigned‚ and how packets are structured and routed. Microsoft Windows Server 2003 provides extensive support for the Transmission Control Protocol/Internet Protocol (TCP/IP) suite‚ as

this article‚ we’ll see how these parts come together to produce bright light for hours on end. Light Basics Light is a form of energy that can be released by an atom. It is made up of many small particle-like packets that have energy and momentum but no mass. These particles‚ called light photons‚ are the most basic units of light. (For more information‚ see How Light Works.) Atoms release light photons when their electrons become excited. If you’ve read How Atoms Work‚ then you know that electrons

lacked protein‚ and three samples containing proteins‚ and using a spectrophotometer we assessed the amount of light absorbed versus the light transmitted‚ based on the principles of the Beer-Lambert Law. The three proteins used included lysozyme‚ protamine sulfate‚ and bovine serum albumin‚ and the three non-protein samples contained either RNA‚ tyrosine‚ and glycylglycylglycine. Standard curves were created to exhibit the linear relationship between the concentration of solute (protein‚ non-protein)

assumptions about her protein needs are unrealistic based on her current weight. Erin’s protein consumption is too low for her weight. This is roughly 13% of her kcalorie intake which is closer to the lower end of the ranges of 10-35 percent. This is unrealistic because she is not consuming enough calories of protein for her weight. If you calculate her weight by height you can clearly she needs more protein. Erin’s weight 118lbs /2.2ib/kg= 54 kg‚ so know take 54kg x 0.8g/kg= 43.2g protein. (Understanding

How Your Heart Works [pic] Your heart is a pump. It keeps blood moving around your body. The blood delivers oxygen and nutrients to all parts of your body‚ and carries away unwanted carbon dioxide and other waste products. The heart has four chambers - two on the left side and two on the right. The two upper chambers are called the atria‚ and the two lower chambers are called the ventricles. The two sides of the heart are divided by a muscular wall called the septum. Each side of the heart

have for protein synthesis? Explanation: The mRNA encodes the amino acid sequence of a protein. During the translation‚ ribosomal RNA combines with other proteins to form a ribosome which amino acids are transported to the ribosome. The combination of mRNA and tRNA converts the mRNA into the amino acid sequence of the protein. Did the two mutations result in a change in the final proteins? If so‚ describe the change. Response/ explanation: A change took place in the final proteins because
