This package includes notes from Thomas, Ramona and Janet's sections for Semester 1 of UCT Biochemistry (MCB3025F). They also include research papers that each lecturer discussed in class.

This document provides an introduction to receptors, hormones, steroids, and steroid-receptor interactions, focusing on gene regulation and cell signaling by steroid receptors.   It discusses the different classes of hormones, including steroid hormones, peptide hormones, and amino acid-derived hormones, and explains how they interact with intracellular or cell membrane-associated receptor proteins in target cells to produce a metabolic or gene expression response.   The notes also des...

This document contains class notes on RNA polymerase II gene regulation, covering transcription initiation, chromatin structure, and transcription condensates. The notes discuss the role of general transcription factors (GTFs) and RNA polymerase II in forming the transcription initiation complex at promoter regions. It explains the packaging of DNA with proteins to form chromatin and the different states of chromatin, including euchromatin and heterochromatin. Additionally, the document de...

This document includes each section taught by Ramona in MCB3025F - Key concepts of protein folding, post-translational modifications and disease, protein transport and disease. It also includes important sections of each research paper issued by the lecturer.

This package includes the collection of notes used to study for the HUB3006F exam (2024 notes). They include a summary from most sections/ the most important sections, as well as important sections highlighted by the lecturers during class. (notes written by student that achieved the Class Award for HUB3006F)

This document provides notes on exercise metabolism, bioenergetics, and the fuels used for exercise, such as carbohydrates, fats, and proteins. It explains energy transfer, coupled reactions, and the role of enzymes in regulating exercise metabolism.   Additionally, the notes cover oxidation-reduction reactions, detailing how they enable the transfer of electrons between molecules

This document provides notes on the neuromuscular junction (NMJ), the specialized site where a motor neuron communicates with a skeletal muscle fiber.   It explains the structure and function of the NMJ, including the role of the terminal boutons, synaptic cleft, and motor end plate. The notes cover the sequence of events involved in neurotransmission at the NMJ, from the arrival of an action potential to muscle contraction.   Additionally, the document discusses key concepts such as e...

This document delves into the science of sleep, exploring the physiology of sleep and circadian rhythms, their importance, and the consequences of sleep deprivation.   It discusses circadian rhythms as endogenously driven 24-hour cycles and their influence on various physiological systems like blood pressure, heart rate, body temperature, melatonin, and growth hormone levels.   The notes further explain the role of the master clock (SCN) and peripheral clocks in controlling circadian r...

This document discusses the relationship between diabetes and exercise, including the impact of physical activity on insulin sensitivity, endothelial function, and the autonomic nervous system. It also addresses the impairments caused by diabetes on exercise tolerance and cardiorespiratory fitness.   The notes further explore the benefits of exercise in managing diabetes, such as promoting weight loss, improving cardiovascular fitness, and reducing oxidative stress and inflammation.   ...

This document focuses on the biochemical structure of tendons, tendon injuries, and the properties of connective tissues. It details the types of musculoskeletal connective tissue, including tendons, ligaments, bones, cartilage, and muscle connective tissues, and explains the importance of connective tissue in preventing diseases and managing musculoskeletal injuries.   The notes cover the structure and function of tendons, the factors contributing to tendon injuries, and the characteristic...
