Bioquímica Repaso Examen 1 Chapter 1: Introduction to Biochemistry 1.1 Biochemistry is a Modern Science • By synthesizing urea‚ Friedrich Wöhler showed that compounds found in living organisms could be made in the laboratory from inorganic substances. He used the inorganic compound ammonium cyanate. • Two major breakthroughs in the history of biochemistry are especially notable: o Roles of enzymes as catalysts o Roles of nucleic acids as information carrying molecules.

The primary purpose of this experiment was to determine the optimum temperature range for the activity of the enzyme lactase. Extreme temperatures can have a detrimental effect on enzymes; very hot temperatures can cause the denaturation in the enzyme‚ which is the loss of protein structure. This causes a change in the shape of the enzyme leading to its inability to perform its function. As previously stated‚ the alternate hypothesis read: the optimal temperature range for lactase activity is between

cm × 1.0 cm) equilibrated with 10 mM Tris-HCl buffer‚ pH 8. The column was eluted at a flow rate of 1 ml / 6 min. The elution profile of gel filtration chromatography is shown in the (Fig: 1). The fractions collected were determined for its total protein concentration and fibrinolytic enzyme activity. The active fraction obtained was pooled together‚ concentrated by lyophilization and used as purified fibrinolytic enzyme for subsequent studies. The summary of purification steps involved for fibrinolytic

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

conflicting thoughts on this‚ and it wasn’t until Edward Buchner experimented on this topic in 1897 that this notion was generally accepted. (Metzler‚ 2001) The term “Enzyme”‚ derived from the Latin phrase “in yeast”‚ is an organic catalyst‚ most often proteins‚ that accelerate specific chemical reactions by lowering the required activation energy necessary for that reaction to occur. One enzyme in particular‚ Acid Phosphatase‚ is a critical enzyme in our every day biological functions. Phosphorus plays

The enzymes involved in DNA replication process are template-directed polymerases that can synthesize the complementary sequence of each strand with extraordinary fidelity. This complex leads to the local denaturation and unwinding of an adjacent A + T rich region of DNA. The interaction of proteins with the origin is what defines the start site of replication and provides a short region of single stranded DNA essential to initiation of synthesis of the nascent DNA strand. Then helicase binds and allows
