Final answer:
Three important types of chemical reactions in human physiology are synthesis (anabolic) reactions, decomposition (catabolic) reactions, and oxidation-reduction (redox) reactions, each playing a vital role in growth, energy production, and metabolism. option a is correct
Step-by-step explanation:
option a is correct Human physiology involves various chemical reactions that are essential for maintaining life. Three important types of these reactions are synthesis reactions, decomposition reactions, and oxidation-reduction (redox) reactions.
- Synthesis reactions, also known as anabolic reactions, are chemical reactions in which two or more simple substances combine to form a more complex product. These are crucial for processes like tissue growth and the synthesis of biomolecules.
- Decomposition reactions, or catabolic reactions, are the opposite of synthesis reactions. They involve the breakdown of complex molecules into simpler ones, releasing energy that is used by the body.
- Oxidation-reduction reactions (redox reactions) include any chemical reaction in which the oxidation state of a molecule, atom, or ion changes by gaining or losing an electron. Redox reactions are fundamental to processes such as cellular respiration and energy production.
Understanding these reactions provides insight into how the human body functions at a molecular level, including energy production, growth, and the metabolizing of food.
Three types of chemical reactions important to human physiology are:
Synthesis: This is a reaction where two or more substances combine to form a more complex substance. An example of synthesis is the production of proteins in the body, where amino acids are joined together.
Decomposition: In this reaction, a complex substance breaks down into two or more simpler substances. An example of decomposition is the breakdown of carbohydrates during cellular respiration to release energy.
Oxidation-reduction (redox): Redox reactions involve the transfer of electrons between reactants. An example of redox reaction in human physiology is cellular respiration, where glucose is oxidized to produce ATP.
