Verified step by step guidance

Understand the question: The problem asks which sugar is primarily converted to glucose in the liver. This involves understanding carbohydrate metabolism and the role of the liver in processing different sugars.
Recall the metabolic pathways: The liver plays a central role in converting various sugars into glucose. Fructose is metabolized in the liver through the fructose metabolism pathway, where it is converted into intermediates like fructose-1-phosphate and eventually into glucose via gluconeogenesis.
Review the other options: Galactose is converted to glucose in the liver through the Leloir pathway. Maltose is a disaccharide composed of two glucose molecules, so it does not require conversion to glucose. Sucrose is a disaccharide composed of glucose and fructose, and its fructose component is metabolized in the liver.
Focus on fructose: Fructose is unique because it is primarily metabolized in the liver, where it is converted into glucose or stored as glycogen. This makes fructose the correct answer to the question.
Summarize the reasoning: Based on the metabolic pathways, fructose is the sugar primarily converted to glucose in the liver, as it undergoes specific enzymatic processes that lead to glucose production.
