Multiple Choice
What is the most abundant inorganic substance in the human body?
A
Calcium phosphate (\(Ca_3(PO_4)_2\))
B
Water (\(H_2O\))
C
Sodium chloride (\(NaCl\))
D
Carbon dioxide (\(CO_2\))
Verified step by step guidance1
Step 1: Begin by understanding the term 'inorganic substance.' Inorganic substances are compounds that generally do not contain carbon-hydrogen bonds, unlike organic compounds.
Step 2: Review the options provided in the question: Calcium phosphate (\(Ca_3(PO_4)_2\)), Water (\(H_2O\)), Sodium chloride (\(NaCl\)), and Carbon dioxide (\(CO_2\)). Identify which of these are inorganic substances.
Step 3: Recall that water (\(H_2O\)) is the most abundant substance in the human body, making up approximately 60-70% of body weight. It is essential for various biological processes, including temperature regulation, nutrient transport, and waste removal.
Step 4: Compare the abundance of water (\(H_2O\)) to other inorganic substances listed, such as calcium phosphate (\(Ca_3(PO_4)_2\)), which is primarily found in bones and teeth, sodium chloride (\(NaCl\)), which is important for electrolyte balance, and carbon dioxide (\(CO_2\)), which is a byproduct of cellular respiration.
Step 5: Conclude that water (\(H_2O\)) is the most abundant inorganic substance in the human body based on its critical role and prevalence compared to the other options.
