AP Bio Exam Question Breakdown: Biotechnology Tools.. Tweet; The AP Biology exam for 2017 is set for the morning of Monday May 8 th. So it’s that time of the year again to begin reviewing past concepts and doing practice exams.. Restriction enzymes.Therefore an enzyme will act on only one type of a specific substrate molecule. Enzymes also reduce the activation energy this is the initial amount of energy that is required to increase the rate of a particular reaction. The rate of a reaction of an enzyme depends on how many enzyme molecules there are.Relate the chemical structure of an enzyme to its specificity and catalytic activity. Design a quantitative experiment to investigate the influence of pH or temperature on the activity of an enzyme. Describe what information concerning the structure of an enzyme could be inferred from your experiments.
An evolutionary biologist hypothesizes that two morphologically similar plant species are not closely related. To test the hypothesis, the biologist collects DNA samples from each of the two plant species and then uses restriction enzymes to cut the DNA samples into fragments, which are then subjected to gel electrophoresis.
Many restriction enzymes have the ability to recognize a 4 to 10 nucleotide base pair palindrome. Once the restriction enzyme cuts the DNA, it creates either a “blunt” or “sticky” end. A “sticky” is a DNA fragment available to become a recombinant DNA molecule, which is the basis of biotechnology.

Restriction Enzymes: Recombinant Dna Essay. Restriction enzymes are used to manipulate DNA sequences to create recombinant DNA by first cutting up the foreign DNA in order to protect the bacteria cell against invading DNA from other organisms. The enzyme is very specific when it comes to identifying a specific DNA sequence.

Essay text: Catalysis is the acceleration of a chemical reaction by means of a substance, called a catalyst that is itself not consumed by the overall reaction. Catalase has one of the highest turnover rates for all enzymes; one molecule of catalase can convert 83,000 molecules of hydrogen peroxide to water and oxygen per second.

Welcome to AP Biology! We have a full and exciting year ahead of us! This course is designed to be the equivalent of an introductory college biology course taken by biology majors during their 1st year. It is my desire for students to see the evidence of our Creator God through our study.
AP Biology Essay Questions The following is a comprehensive list of essay questions that have been asked on past AP exams. The questions are organized according to units. Unit 1 (Basic Chemistry and Water) 1. The unique properties (characteristics) of water make life possible on Earth. Select three properties of water and: a.
A simple example of the importance of enzymes in digestion is lactose- intolerance. Lactose is a sugar found in milk, and is digested by an enzyme found in the intestines called lactase. A lack of this enzyme can result in lactose- intolerance, whereby the undigested lactose is fermented by bacteria causing a host of intestinal complications.
