Introduction to Enzyme Kinetics01:19

Introduction to Enzyme Kinetics

20.2K
Enzyme kinetics studies the rates of biochemical reactions. Scientists monitor the reaction rates for a particular enzymatic reaction at various substrate concentrations. Additional trials with inhibitors or other molecules that affect the reaction rate may also be performed.
The experimenter can then plot the initial reaction rate or velocity (Vo) of a given trial against the substrate concentration ([S]) to obtain a graph of the reaction properties. For many enzymatic reactions involving a...

Acid and Bases: Ka, pKa, and Relative Strengths02:35

Acid and Bases: Ka, pKa, and Relative Strengths

26.8K
This lesson delves into a critical aspect of the relative strengths of acids and bases. The strength of an acid is evaluated by the acid dissociation into its conjugate base and a hydronium ion in water. The complete dissociation of a strong acid is confirmed with a very high concentration of hydronium ions. As a result, an incomplete dissociation process affirms a weak acid. Therefore, the equilibrium is in the forward direction for strong acids and backward for weak acids in these reactions.

Catalytically Perfect Enzymes01:07

Catalytically Perfect Enzymes

4.0K
The theory of catalytically perfect enzymes was first proposed by W.J. Albery and J. R. Knowles in 1976. These enzymes catalyze biochemical reactions at high-speed. Their catalytic efficiency values range from 108-109 M-1s-1. These enzymes are also called 'diffusion-controlled' as the only rate-limiting step in the catalysis is that of the substrate diffusion into the active site. Examples include triose phosphate isomerase, fumarase, and superoxide dismutase.

Leveling Effect and Non-Aqueous Acid-Base Solutions02:11

Leveling Effect and Non-Aqueous Acid-Base Solutions

8.2K
This lesson defines the leveling effect in acidic and basic solutions and its role in aqueous and non-aqueous solutions. It is essential to understand the competing nature of various species in a chemical system.
The Leveling Effect of a Solvent
A generic acid (HA) reacts with the generic base (B-) to yield the corresponding conjugate base (A-) and conjugate acid (HB):

Protein Folding01:25

Protein Folding

8.1K
Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.
Protein Structure Is Critical to Its Biological Function
Proteins perform a wide range of biological functions such as catalyzing chemical reactions, providing...

Introduction to Mechanisms of Enzyme Catalysis01:13

Introduction to Mechanisms of Enzyme Catalysis

8.3K
For many years, scientists thought that enzyme-substrate binding took place in a simple "lock-and-key" fashion. This model stated that the enzyme and substrate fit together perfectly in one instantaneous step. However, current research supports a more refined view scientists call induced fit. The induced-fit model expands upon the lock-and-key model by describing a more dynamic interaction between enzyme and substrate. As the enzyme and substrate come together, their interaction causes...

Area of Science:

  • Biochemistry Education
  • Educational Assessment
  • Pedagogical Innovation

Background:

  • Traditional exam-based assessments can induce test anxiety and may not optimize knowledge retention.
  • Specifications grading offers an alternative by focusing on demonstrated mastery of specific skills through frequent, low-stakes assessments.
  • This study explores the implementation of specifications grading in a higher education science setting.

Purpose of the Study:

  • To evaluate the effectiveness of specifications grading in an upper-level biochemistry course.
  • To assess student attitudes and perceptions toward specifications grading.
  • To correlate student performance with their perceptions of learning under this assessment model.

Main Methods:

  • Specifications grading was implemented, incorporating 12 short quizzes, laboratory exercises, and a cumulative final exam.
  • Student attitudes were measured using surveys administered at three points during the semester.
  • Student performance on quizzes was compared to performance on the final exam.

Main Results:

  • Student surveys indicated overall favorable opinions of the specifications grading approach.
  • Performance analysis demonstrated that students learned and retained course material effectively.
  • A strong correlation was observed between students' perceptions of their learning and their performance on specifications grading tools.

Conclusions:

  • Specifications grading is an effective strategy for assessing student learning in biochemistry.
  • This assessment method can enhance student enthusiasm and engagement in upper-level science courses.
  • Specifications grading positively impacts both student performance and their perception of learning.
