Biology Exam Review Unit One – Biochemistry What is an isotope? Isotope - An isotope is all atoms of the same element that have the same number of protons‚ but they may have different numbers of neutrons in the nucleus. - This means that all atoms with the same atomic number can have different atomic masses. - Because they have the same number of protons and electrons‚ they behave exactly the same in chemical reactions. Radioisotope - The nuclei of some isotopes of an element are unstable

deciding what should happen inside the city (control centre). Ribosomes- this is the industrial area of the city‚ creating building materials to extend and develop the city (proteins). Rough Endoplasmic Reticulum- these are couriers who collect the materials from the industrial site and take it to where it is needed (carry proteins). Smooth Endoplasmic Reticulum- another industrial site which creates packages to send and communicate with other cities (steroids). Mitochondria- the electricity generator

Respiration: We need oxygen at the cellular level for this to be complete. Why do you need oxygen? What is your body trying to do? Your body needs to produce energy‚ which is why you go through these metabolic processes‚ and that’s ultimately why you need oxygen. So we are trying to produce ATP as our energy source. So ultimately your energy cannot be created‚ it only changes form‚ so where does that energy come from in your body? We’re going to convert it into ATP‚ because your cells need ATP to do work

has is to increase his protein needs to aid in the wound healing process and to increase his fluid needs since fluids are lost in burn wounds (Namdar T. et al‚ 2010). The two main proteins that Joe needs are glutamine and arginine because they are the two main essential amino acids that assist burn victims in recovery (Wolfe R.). Based on those pertinent nutritional problems‚ Joe has inadequate protein intake (NI-52.1) related to protein losses as evidence by a total protein level of 4.7 and an albumin

Protein Article Search I reviewed “6 Biggest Nutritional Problems Solved” (2008) written by Chris Aceto and Eric Velazquez on the subject of amino acids and how they relate to athletics. The authors believe body builders commonly go overboard in their quest for muscular bodies and neglect key ingredients necessary for muscle production. This relates to amino acids because the authors suggest that athletes frequently leave out fats and proteins made from amino acids. The authors state that

Sam Rausser Wednesday‚ August 17‚ 2011 3:38 PM Once glucose is made‚ glucose molecules can be converted (by plants) to… 1) monosaccharides‚ like fructose 2) Disaccharides a. Maltose (glu‐glu) seeds b. Sucrose (glu‐fru) sugar cane‚ sugar beets 3) Polysaccharides a. Starch‚ food storage in roots (chains of glucose) b. Cellulose‚ plant structure (chains of glucose) 4) Amino Acids a. Glucose + N from ground 5) Lipids‚ specifically oils which are energy source in seeds & phospholipids found in membranes

Determination of the presence of carbohydrates and protein in aqueous solution samples Objectives To determine the presence of starch‚ glycogen‚ reducing sugar‚ peptide‚ and proteins by utilizing Iodine test‚ Benedict test‚ and Biuret test. Introduction The purpose of this experiment was to identify the presence of macromolecules by using various positive and negative controls. The principle building blocks of living organisms are essentially constructed by carbon-containing

polymerizing the solution? How does the percentage of acrylamide effect the migration of proteins (ex: 4% gel vs. 18% gel)? The percent acrylamide refers to the size of the pores as percent acrylamide increases the size of the pores decreases. 2. Describe the purpose of each loading buffer ingredient added to protein samples for SDS-PAGE analysis (hint- there are 4 ingredients). 3. You purified protein X via affinity chromatography (no diafiltration step performed) and ran an SDS-PAGE gel

related process are known as facilitated diffusion. To facilitate something it means to make something easier and the protein channels in the cell membrane help to assist in transporting molecules such as glucose and urea into and out of cells. The number of channel proteins capable of allowing the materials through is important here‚ aswell as the concentration gradient. Each of the protein channels have a shape which contains a special receptor site for the molecule to be transported and change shape
