Anatomy and Physiology is a dynamic textbook for the two-semester human anatomy and physiology course for life science and allied health majors. The book is organized by body system and covers standard scope and sequence requirements. Its lucid text, strategically constructed art, career features, and links to external learning tools address the critical teaching and learning challenges in the course. The web-based version of Anatomy and Physiology also features links to surgical videos, histology, and interactive diagrams.
This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Mosquito-borne illness kills more than 700,000 people per year. Often these pathogens reside in the mosquito gut, where they may be impacted by their diet and gut microbiome. But there are gaps in the research into these impacts. Specifically, most studies into mosquito sugar metabolism focused on blood diets, but only female mosquitos drink blood, while both sexes eat plant sugars like nectar and sap. Similarly, most mosquito microbiome research focused on bacteria, largely missing the potential role of gut fungi, or the mycobiome. To narrow these gaps, researchers examined fructose metabolism in Asian tiger mosquitoes using 13C-metabolomics and stable isotope probing. While female and male mosquitos had distinct metabolic pathways, the active fungal groups in both sexes after fructose ingestion had a mix of competitive and synergistic interactions. There was also evidence of cross-feeding interactions, where one microbial species produces metabolites that other microbes use..."

We are happy to welcome you to our second Open Educational Resource (OER) textbook, Biochemistry Free For All. Biochemistry is a relatively young science, but its rate of growth has been truly impressive. The rapid pace of discoveries, which shows no sign of slowing, is reflected in the steady increase in the size of biochemistry textbooks. Growing faster than the size of biochemistry books have been the skyrocketing costs of higher education and the even faster rising costs of college textbooks. These unfortunate realities have created a situation where the costs of going to college are beyond the means of increasing numbers of students.
This course examines the chemical and physical properties of the cell and its building blocks, with special emphasis on the structures of proteins and principles of catalysis, as well as the chemistry of organic / inorganic cofactors required for chemical transformations within the cell. Topics encompass the basic principles of metabolism and regulation in pathways, including glycolysis, gluconeogenesis, fatty acid synthesis / degradation, pentose phosphate pathway, Krebs cycle and oxidative phosphorylation.
Course Format
This OCW Scholar course, designed for independent study, is closely modeled on the course taught on the MIT campus. The on-campus course has two types of class sessions: Lectures and recitations. The lectures meet three times each week and recitations meet once a week. In recitations, an instructor or Teaching Assistant elaborates on concepts presented in lecture, working through new examples with student participation, and answers questions.
MIT students who take the corresponding residential class typically report an average of 10–15 hours spent each week, including lectures, recitations, readings, homework, and exams. All students are encouraged to supplement the textbooks and readings with their own research.
The Scholar course has three major learning units, called Modules. Each module has been divided into a sequence of lecture sessions that include:
Textbook Readings
Lecture Notes or Storyboards
A video by Professor JoAnne Stubbe or Professor John Essigmann
Problem Sets and solutions
To help guide your learning, each of these problem sets are accompanied by Problem Solving Videos where Dr. Bogdan Fedeles solves one of the problems from the set.
Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.
This resource provides a lab procedure and fillable form pdf lab answer sheet for use in an online biology or nutrition course. Students will need access to a computer and a scale for taking their body weight.
Attributions are provided at the end of the laboratory write-up.
Please refer to the "Completing Lab Reports in Canvas Orientation Exercise" in OER Commons also authored by me (Tina B. Jones) for student instructions on downloading, completing, and uploading the fillable form answer sheets in Canvas.
