Comprehensive Review of Cellular Structures and Processes in Biology

This review focuses on key cell structures including lysosomes, mitochondria, and the endoplasmic reticulum. It explores energy-requiring processes such as active transport, glycolysis, and the Krebs cycle, while highlighting the differences between autotrophs and heterotrophs. The review also examines cell junctions like tight junctions and the effects of hypotonic solutions on animal cells. Additionally, cyclic electron flow and the role of NADPH are discussed in the context of photosynthesis. Ideal for students preparing for biology exams, this overview consolidates essential concepts.
