What pH must organisms maintain?
Understand the Problem
The question is asking about the specific pH levels that organisms need to maintain for proper functioning. It addresses the concept of homeostasis and the importance of pH balance in biological systems.
Answer
Near neutral pH (7)
The final answer is near neutral pH (7) in the blood and body tissues, specifically around 7.35 to 7.45 in humans.
Answer for screen readers
The final answer is near neutral pH (7) in the blood and body tissues, specifically around 7.35 to 7.45 in humans.
More Information
Blood and tissue pH in humans are tightly regulated between pH 7.35 and 7.45, crucial for enzyme function and metabolic processes.
Tips
A common mistake is thinking that the blood pH should be exactly 7. It is actually slightly alkaline at 7.35-7.45.
