Inorganic Molecules
What is the most abundant inorganic molecule in the human body?
What is water?
What percentage of an adult's body weight is water?
What is about 60%
What is the difference between a compound and a mixture?
A compound creates a new substance with its own properties, while a mixture retains the properties of its components.
Why is oxygen essential for cellular respiration?
What is Oxygen that helps break down nutrients to release energy.
What ion is released by acids when dissolved in water?
What is a hydrogen ion (H+)?
Name two inorganic substances essential for cellular respiration.
What are oxygen and carbon dioxide?
What percentage of an adult's body weight is water?
What is fifty percent or more?
Provide an example of a colloid in the human body.
What is gelatin or thyroid hormone?
What is the waste product of cellular respiration?
What is carbon dioxide?
What defines a strong acid?
A strong acid completely dissociates into H+ and another ion in solution.
What term describes a substance that does not contain carbon?
What is an inorganic compound?
Why is water considered a lubricant in the body?
Water reduces friction between body tissues, especially in joints and around organs.
What type of mixture is blood considered?
What is a suspension?
How does carbon dioxide contribute to acid-base balance in the body?
What helps regulate pH levels in the blood?
What is a common base found in household cleaners?
What is sodium hydroxide (NaOH)?
What is the role of carbon dioxide in the body despite being a waste product?
What is maintaining acid-base balance?
Explain how water helps in temperature regulation in the body.
Water absorbs and releases large amounts of heat without changing temperature, helping to maintain stable body temperature.
How does a solution differ from a suspension?
What is a solution that has particles that dissolve completely, while a suspension has larger particles that can settle out?
What happens to cells when they do not receive enough oxygen?
They cannot produce enough energy, leading to cell damage or death.
What happens when an acid is mixed with a base?
They neutralize each other, forming water and salt.
Give an example of an inorganic acid found in the human body.
What is hydrochloric acid (HCl)?
What happens to sweat when it evaporates from the skin?
It carries away heat, helping to cool the body down.
What is an example of suspension mixture you encounter in the kitchen?
What is salad dressing?
Describe the relationship between oxygen and glucose in cellular respiration.
Oxygen is used to break down glucose, releasing energy and producing carbon dioxide as a byproduct.
How do bases affect the pH of a solution?
Bases increase the pH by accepting hydrogen ions.
