Question

Do inorganic molecules affect living things?

Answer 1

Inorganic molecules are small molecules with few atoms and linkages that include few or no carbon atoms that dissolve rapidly in water. Inorganic molecules lack carbon-hydrogen bonds in their composition and contain a wide number of different elements. Salts, minerals, and metals, for example, are frequently found in it.

Complete answer
Living things are impacted by inorganic molecules. Some are necessary for life, while others have the potential to kill us.
For instance, water accounts for over $70\%$ of the human body's weight. This water is found intracellularly as well as between the body's tissues and organs. Water is the primary component of many of the body's lubricating fluids. Food moves more easily through the digestive tract with the help of water. It also defends the cells and organs from physical harm, supports the brain, and protects the nerve tissues of the eyes.
For the vast majority of living species on the planet, oxygen is the most significant inorganic molecule. Organisms require oxygen in order to release energy from organic compounds. Photosynthesis is the process through which plants produce oxygen in the atmosphere. Living creatures take in oxygen, execute respiration, and carry out other bodily metabolic functions.
Mineral salts are also important to living things. NaCl dissolves thoroughly in water and splits into sodium and chloride. Water molecules break down into ions when they pull away from these molecules. These ions are necessary for the transmission of nerve impulses and the contractions of muscles.

Note:
Inorganic molecules have a big impact on the living organisms. Water and oxygen are very essential for living things as they play a significant role in maintaining homeostasis. The most important compounds for an organism are water, mineral salts, molecular oxygen, and carbon dioxide.
