What This Document Is
This is a practice midterm exam for CHEM 481 Biochemistry at Brigham Young University, specifically for Section 001 taught by Dr. James Moody during the Winter 2020 semester (Version 3). It’s designed to help students assess their understanding of core biochemistry concepts covered in the first portion of the course. The exam is divided into two parts: multiple-choice questions and free-response questions.
Why This Document Matters
This practice exam is a valuable resource for students preparing for the actual midterm. It allows students to familiarize themselves with the exam format, question types, and the level of difficulty they can expect. Working through this practice exam can identify knowledge gaps and areas needing further study. It’s most useful when used *before* the actual midterm, as a diagnostic tool to guide focused review.
Common Limitations or Challenges
This document is a *practice* exam, not the actual exam. While representative, it won’t cover every single topic or question style that may appear on the official midterm. Relying solely on this practice exam without reviewing course lectures, readings, and homework assignments will likely result in an incomplete understanding of the material. It also does not include answer keys for the free response section.
What This Document Provides
This document includes:
* 21 multiple-choice questions covering topics such as protein structure, hemoglobin function, amino acid properties, and peptide characteristics. The multiple-choice section specifies a unique scoring system where partial credit is awarded for correct choices and points are not deducted below zero.
* A titration curve and associated questions (questions 3-8) testing understanding of amino acid properties and pKa values.
* A set of peptide sequences (questions 9-12) and questions related to their properties and potential interactions.
* General instructions regarding exam format and scoring.
This preview *does not* include the answers to the free-response questions, nor does it provide detailed explanations for any of the questions. It also does not include the full set of 22 free-response questions.
