Gustavo Carro BIO-105 Human vertebral column In human anatomy‚ the vertebral column is a column usually consisting of 24 articulating vertebrae and 9 fused vertebrae in the sacrum and the coccyx. It is situated in the dorsal aspect of the torso‚ separated by intervertebral discs. It houses and protects the spinal cord in its spinal canal. There are normally thirty-three (33) vertebrae in humans‚ including the five that are fused to form the sacrum (the others are separated by intervertebral

protein structure would be tertiary‚ or quaternary. (b) Discuss how the structure of a protein affects the function of TWO of the following. • Muscle contraction • Regulation of enzyme activity • Cell signaling Enzymes bind to their substrates at a specific point called the active site. The regulation of enzyme activities mostly involves the inhibition of substrates‚ and this inhibition is divided into two types. The first type‚ competitive inhibitor‚ binds the inhibitors at the active site

reaction involves enzymes. So to understand how bleach works‚ we first understand how enzymes work. Enzymes Enzymes are the most important thing in our lives‚ it makes the world go ‘round! Enzymes are proteins that acts as catalysts and help combine or break down hydrogen peroxide. Imagine a pen with ink inside it‚ when you write‚ ink comes out‚ right? You can draw‚ you can write‚ then when you finish and get your pen off of the paper‚ the ink stops coming out. Enzymes are like that‚ they

Is Grade Retention Beneficial for Students? Is Grade Retention Beneficial for Students? Grade retention‚ also known as “flunking” or being held back‚ is one of the most common ways to raise educational standards. Retention occurs when teachers and administrators and/or parents do not feel the student is ready to be promoted to the next grade due to academic or maturity reasons. The student then has to repeat the previous year until they pass or are prepared for

The bonding of an enzyme to its substrate forms an enzyme-substrate complex. The catalytic action of the enzyme converts its substrate into the product or products of the reaction. Each reaction is extremely specific‚ distinguishing between closely related compounds‚ including isomers. For example‚ the enzyme sucrase will only act on sucrose and will not bind to any other disaccharide. The molecular recognition of enzymes is due to the fact that they are proteins‚ which are defined as being macromolecules
