related to one and another as an ionized or free calcium‚ the complex calcium and non-diffusible calcium where the calcium bound to plasma protein (Wills‚ Lewin‚ & Hospital‚ 1971). The level of calcium is closely regulated by the normal total calcium and normal ionized calcium. The total amount of calcium in the body varies with the level of serum albumin‚ a protein to bind with calcium. A biological effect of calcium is measured by the amount of ionized calcium‚ total calcium. The calcium is not a

There are not any real safety concerns for this lab other than making sure correct use and care of the microscope is used.

Introduction The purpose of this experiment is to identify three unknown enzymes. This is done by using different temperature and pH to affect the function of the enzyme‚ which ultimately‚ will affect how much maltose is produced. Enzymes are proteins that help catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process are called substrates‚ and the enzyme converts them into different molecules‚ the products. Enzymes are extremely selective for their

Introduction: Mitosis occurs in all eukaryotic cell tissues and produces genetically identical daughter cells with a complete set of chromosomes. In humans‚ mitosis produces somatic cells that are diploid‚ which means they contain two non-identical copies of each of the twenty-three chromosomes. One copy is derived from the person’s mother and the other from the person’s father. Meiosis‚ on the other hand‚ occurs only in testis and ovary tissues‚ producing sperm and ova (eggs). The gametes that

In fermentation the pyruvate is converted into ethyl alcohol‚ through the oxidation of the 2 NADH molecules‚ which returns them to two NAD+’s (Freeman‚ 2011). Oxidation is the loss of an electron in this case H+. We used information from previous labs in which we tested

large to penetrate the molecular weight cut off pores and no simple diffusion can occur. So it seemed like the easiest way for a solute to pass through a semipermeable membrane was‚ if it either was small enough to pass or had some sort of carrier protein that helped it along. We expected to see continuous results that do not have much difference in the five experiments that are to be performed. Experiments were conducted in order to gain a better understanding of a cell’s selectively permeable membrane

lysis was present; therefore‚ P. larvae was isolated. Isolating DNA from the Pure Colonies Grown In addition‚ DNA were isolated from the colonies grown and its concentration was 33.6 ng/uL and the A260/280 value was 1.84. Next‚ an agarose gel electrophoresis was conducted to see if any DNA fragments were present. A band was visible and that validates that genomic DNA has been isolated.

conclusion was that catalase reacts faster in warm temperatures that are neither freezing nor boiling‚ catalase performs well in lower concentrations than the substrate‚ and catalase prefers neutral pH levels around 7. Introduction Enzymes are proteins that catalyze metabolic reactions vital for the survival and functioning of cells [1]. Without enzymes‚ metabolic processes would occur at unfeasible rates. Catalase is a naturally occurring enzyme that breaks down hydrogen peroxide into water and

Lab Report Part II Purpose: To be familiarized with the science and techniques used to identify different types of bacteria based on their DNA sequences. Background Information: The process begins with preparing a sample. Successful identification starts with using a sample that is considered to be good. The first step is to pick up a single colony and drop it into a microcentrifuge tube. A buffer is used to dissolve the cell wall in order to extract bacterial DNA. This step may take several hours
