What sequence is represented by the mnemonic "Her Grandma Puts Paint (in) Kettles"?

What sequence is represented by the mnemonic "Her Grandma Puts Paint (in) Kettles"?

• A. Pathway of glucose metabolism
• B. Enzymes in irreversible steps
• C. Substrates of the Krebs cycle
• D. Products of glycolysis

Answer: (B)

The mnemonic "Her Grandma Puts Paint (in) Kettles" represents the key enzymes involved in the irreversible steps of glycolysis. In glycolysis, there are several steps where certain reactions are irreversible due to significant energy barriers or where the products cannot easily revert to substrates; these are catalyzed by specific enzymes. The mnemonic can be broken down as follows: - "Her" - Hexokinase - "Grandma" - Glucokinase (which is similar, though more relevant in the liver) - "Puts" - Phosphofructokinase (PFK) - "Paint" - Pyruvate kinase - "(in) Kettles" - describes that these steps are crucial in the glycolytic pathway. These irreversible steps are crucial regulatory points in glycolysis, effectively controlling the flow of metabolites through the pathway. Identifying these specific enzymes is important for understanding metabolic regulation and energy production in cells. The other choices refer to different metabolic pathways or components not directly aligned with the mnemonic, highlighting that the focus here is clearly on the role of specific enzymes in glycolysis.
