The corpus callosum is the largest white matter structure in the brain, consisting of over 200 million axons. It forms a broad, flat band located deep in the longitudinal fissure (the cleft between the two hemispheres). Its primary function is to serve as the main communication pathway, allowing the left and right cerebral hemispheres to share information, coordinate activities, and integrate sensory, motor, and cognitive functions.

Explanation:
Peter Mitchell proposed the chemiosmotic theory (1961), explaining that a proton gradient across a membrane drives ATP synthesis. Krebs discovered the citric acid cycle, Calvin the Calvin cycle, Lipmann discovered coenzyme A.

Explanation:
Lysosomes are single-membrane-bound organelles containing hydrolytic enzymes. Mitochondria, chloroplasts, and the nucleus are double-membrane-bound. Peroxisomes, vacuoles, and the endoplasmic reticulum are also single-membrane structures. The single membrane of lysosomes helps maintain an acidic pH (5.0) for enzyme activity and protects the cell from autolysis.
