Questions: True or False Question In strict aerobes and some anaerobes, pyruvic acid enters the Krebs cycle after it is converted to acetyl CoA. True False

The answer is True: In strict aerobes and some anaerobes, pyruvic acid enters the Krebs cycle after it is converted to acetyl CoA.

Explanation:

• Pyruvic acid, which is the end product of glycolysis, must be converted into acetyl CoA before it can enter the Krebs cycle (also known as the citric acid cycle or TCA cycle). This conversion is a crucial step in cellular respiration.
• In strict aerobes, which require oxygen for survival, this process is a part of aerobic respiration.
• Some anaerobes, which do not require oxygen, can also convert pyruvic acid to acetyl CoA and utilize the Krebs cycle under certain conditions, although they may rely on other metabolic pathways as well.
• Therefore, the statement is true as it accurately describes the metabolic process in these organisms.
