Study Notes
The topic of "Standard 9 Science" enricly explores the subtopics of cell structure and functions, chemical reactions, and forces and motion. These subtopics are fundamental to the science of biololgical processes and the behavior of matter.
Cells are the basic structural and functional unit of life, discovered by Robert Hooke and are supported and organized by the cytoskeleton, which is made up of microtubules and other proteins. Cells can be of two types: Prokaryotic and Eukaryotic, with the presence of a cell wall in plant cells, made of cellulose, and a cell membrane in both types of cells, made up of a phospholipid bilayer membrane and supported by actin and other proteins for optimal chemical production, use, and degradation.
Chemical reactions are an inesoluble process in cells, where energy is released from the controlled breakdown of food molecules, such as glucose, through processes like glycolysis and the citric acid cycle to generate energy-rich molecules like ATP and NADH. These molecules are used throughout the cell to power metabolism and construct new cellular components and are catalyzed by enzymes, which lower the energy barrier required for reactions to begin without force.
The subtopic of forces and motion is also an inesoluble topic in science, where matter can be in different states, such as Solid, Liquid, Gas, and Plasma and can be held together by forces of attraction or by the presence of a semipermeable membrane for water flow in the process of osmosis.
In the process of cellular respiration, cells absorb glucose from food and burn it to produce energy through a process called oxidative phosphorylation, where electrons from NADH and FADH2 are transported through membrane protein complexes and ultimately to oxygen, forming water and ATP.
