Which statement about acids is true?
A
They have little physiological effect on chemical reactions in cells.
B
Weak acids only dissociate partially in solution.
C
When high in the body, they cause alkalosis.

Most acid is a result of ingestion with food.
E
Our bodies have few ways to deal with excess amounts of acids.
Verified step by step guidance1
Understand the role of acids in the body: Acids are crucial for various physiological processes, including digestion and cellular metabolism. They can influence chemical reactions significantly.
Learn about weak acids: Weak acids do not fully dissociate in solution, meaning they release fewer hydrogen ions compared to strong acids. This partial dissociation is important for maintaining pH balance in the body.
Explore the concept of alkalosis: Alkalosis is a condition where the body's pH becomes too high (too alkaline). It is typically caused by a decrease in acid levels or an increase in bicarbonate, not by high levels of acids.
Consider the sources of acids: While some acids are ingested with food, most acids in the body are produced internally, such as carbonic acid from cellular respiration.
Examine the body's mechanisms for handling acids: The body has several systems to manage excess acids, including the respiratory system (which can expel CO2) and the renal system (which can excrete hydrogen ions and reabsorb bicarbonate).
