and Enzyme Concentration on Catecholase Activity Abstract: This experiment examined the effect on how the changes in pH balance of potato juice affected the enzyme activity‚ structural stability and solubility. Introduction: Enzymes are macromolecules that allow chemical reactions to occur. They function as biological catalysts. A catalyst is a substance that is involved in‚ but not changed by or consumed in‚ a chemical reaction. The amount of energy required for a reaction to take place is

For this experiment‚ there will be an optimal point for each factor. I believe that the optimal temperature for the enzyme sucrase will be 37°C because that is the point where the temperature increases the rate of reaction to its greatest point without denaturing it. For the pH test‚ I think that the optimal pH for sucrase will be the pH of 7 because it is neutral so it won’t affect the charge in a negative or positive way. For the denaturation test‚ I think that the optimal treatment for the enzyme

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA? DNA is composed of two polynucleotide strands wound together into a structure known as a double helix. Each nucleotide consists of a sugar base .Nucleotides form together creating a sugar phosphate backbone to each strand. There are three forms of DNA that differ significantly. The most common‚ B form‚ is the structure most people have heard of. It consists of the right

microfilament. Therefore‚ I got wrong in some multiple choices of this midterm. I went back to the notes and read them again after seeing my midterm which can help me to clarify and solidify my understanding. I also learned the structure of different macromolecules. It seems like such a tip as I learned these in Biology 12‚ but‚ there is additional knowledge of applying those structures. I found it’s interesting to recognize those structures through different functional groups. In this class‚ so far‚ I used

different amino acid‚ causing a mutation that could devastate the organism. Recently‚ scientists have discovered a new method to edit and repair DNA that could hopefully complement the existing method of CRISPR. DNA is a type of nucleic acid‚ a macromolecule found within a cell. DNA itself consists of two strands of nucleic acid in a double helix structure. Each of these strands consists of nucleotides‚ which in turn are made up of a pentose sugar‚ a nitrogenous base‚ and a phosphate group. The “code”

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA stands for Deoxyribonucleic acid and looks like a spiral. The spiral is also known as a double helix. The strands are made up of our genetic information‚ composed of genes and chromosomes. There are four bases divided among purines and pyrimidines. On the purines there are Adenine (A) and Guanine (G). On the pyrimidines there are Cytosine (C) and Thymine (T). The

The outer layer or the cell controls the movement which goes in and out of the cell. The cell membrane holds the cell together‚ but has very tiny holes to allow products to move in

How did his body manage his fuel reserves? What macromolecules did his body look to first for energy? What did his body do when this resource ran out? It rationed them the best it could. It looked for calories first‚ and when this ran out he started to use his body fat as energy.
