2.1 EnzymesEnzymes are biological catalysts made of protein.2.2 PhotosynthesisPhotosynthesis is the process by which green plants make their own food using sunlight.2.2 RespirationRespiration is the enzyme-controlled, catabolic release of energy from food, primarily glucose, within living cells.2.3 Cell Division and CancerA mutation is a change in the amount or structure of the DNA (or chromosomes) of an organism.2.3 DNA Replication, Protein Synthesis, and MutationsDNA replication occurs during interphase of the cell cycle, before nuclear division begins.2.4 Plant ResponsesPlants are sessile organisms anchored in soil.2.4 The Musculoskeletal SystemThe human body responds to environmental changes using four coordinated systems: the nervous system, the endocrine system, the immune system, and the…2.4 The Nervous SystemThe nervous system is the body's rapid communication network, coordinating swift responses to internal and external environmental changes to maintain…2.4 The Endocrine SystemA gland is an organ or cluster of cells that synthesises and secretes specific chemical substances. The human body contains two distinct categories of glands:2.4 HomeostasisHomeostasis is the maintenance of a constant internal environment in an organism.2.4 ImmunityYour body is constantly exposed to organisms that can make you ill.2.5 Reproduction: HumanHuman reproduction is sexual: a sperm from the father and an egg from the mother join together, and the single cell that results grows into a baby inside…2.5 Reproduction: PlantIn this topic you will learn the parts of a flower and what each one does, how pollen is moved from one flower to another by insects or by wind, how to…2.6 Transport Across MembranesEvery living cell is enclosed by a cell membrane, also known as the plasma membrane. We describe its structure using the fluid mosaic model.2.6 The Urinary SystemEvery minute, approximately one-fifth of your cardiac output passes through the kidneys via the renal arteries.2.6 The Digestive SystemThe digestive system consists of the alimentary canal, a continuous muscular tube through which food travels, and several accessory organs that produce…2.6 The Breathing SystemThe breathing system is divided into the upper respiratory tract (nose, pharynx, and larynx, located in the head and neck) and the lower respiratory tract…2.6 The Circulatory System and BloodBlood is a liquid connective tissue made up of cellular elements suspended in a pale yellow fluid called plasma, which accounts for roughly 55% of total…2.6 Plant Structure and TransportPlant structure and transport examines how flowering plants absorb raw materials from soil and air, distribute water, minerals, and photosynthetic products…
