AS Level AQA unit 1: Topic 3 Movement In and Out of Cellssupe-saiyan
This document summarizes key concepts about membranes, absorption, and cholera. It discusses the structure and functions of lipids and phospholipids in cell membranes. It describes different types of membrane transport including diffusion, facilitated diffusion, active transport, and osmosis. It then focuses on absorption in the small intestine and how glucose is absorbed. The document explains how cholera causes diarrhea by secreting toxins that open chloride channels. It concludes by describing oral rehydration therapy used to treat cholera-induced dehydration.
This document summarizes key aspects of lung anatomy and function and several lung diseases. It describes how the trachea, bronchi, and bronchioles transport air to and from the alveoli for gas exchange. The roles of the diaphragm and intercostal muscles in inhalation and exhalation are also outlined. Several lung diseases are then summarized, including tuberculosis, pulmonary fibrosis, asthma, and emphysema. For each disease, the causes, effects on lung function, and common symptoms are concisely explained.
This document summarizes key concepts about immunity and the immune system. It discusses the types of pathogens that can infect the body, how pathogens enter and cause disease, and the body's physical and immune responses. It describes phagocytosis, lymphocytes, and the specific immune responses of T cells and B cells. It also covers antibodies, monoclonal antibodies, antigen and antibody detection tests, vaccines, and antigenic variation.
AS Level AQA unit 1: Topic 3 Cells and Microscopessupe-saiyan
Microscopes use wavelengths of light or electrons to visualize cells and organelles. Light microscopes can distinguish objects 0.2um apart while electron microscopes have much higher resolution down to 0.1nm. Specimens are cut thin and stained for contrast. Fractionation separates cell components through homogenization, centrifugation, and differential sedimentation based on density. Key organelles include the nucleus which houses DNA, mitochondria which perform aerobic respiration, the endoplasmic reticulum which modifies and transports proteins, and lysosomes which digest materials.

AQA Unit 1: Enzymes and the Digestive Systemsupe-saiyan
The document summarizes topics related to the digestive system and enzymes. It describes the roles of different organs in the digestive system like the mouth, stomach, and small intestine. It explains the processes of digestion like mechanical and chemical digestion. It discusses the different types of enzymes involved in digestion of carbohydrates, lipids, and proteins. Finally, it covers topics like protein structure, denaturation, and types of proteins like fibrous and globular proteins.
Arvind Kaboo has over 23 years of experience in maintenance roles. He is currently the Maintenance Manager at Mayur Uniquoters Limited, where he oversees a team of 22 people responsible for preventative and reactive maintenance.
