Total fat oxidation depends on the percentage of energy from fat oxidation and the rate of energy expenditure (intensity). A point worth noting is that while the percentage of fat being oxidised is lower in high-intensity (85% V̇O 2peak R) exercise, it is at a similar rate as at low-intensity (25% V̇O 2peak R) exercise (0.4 and 0.5 g/min,

The basic answer is: to get energy out of that glucose molecule! Here is the glucose breakdown reaction we saw at the beginning of the article: C 6 H 12 O 6 + 6 O 2 → 6 CO 2 + 6 H 2 O Δ G = − 686 kcal/mol. Which we can rewrite a bit more clearly as: C 6 H 12 O 6 + 6 O 2 → 6 CO 2 + 6 H 2 O + energy!
Abstract. Carbohydrates are the preferred substrate for contracting skeletal muscles during high-intensity exercise and are also readily utilized during moderate intensity exercise. This use of carbohydrates during physical activity likely played an important role during the survival of early Homo sapiens, and genes and traits regulating

Reductions in exogenous carbohydrate oxidation following energy restriction appear to result from lower insulin sensitivity and glucose uptake. Exogenous carbohydrate may thus be an effective intervention to sustain performance following short-term energy-adequate carbohydrate restriction but may not be an effective ergogenic aid when glycogen stores

Lipid metabolism entails the oxidation of fatty acids to either generate energy or synthesize new lipids from smaller constituent molecules. Lipid metabolism is associated with carbohydrate metabolism, as products of glucose (such as acetyl CoA) can be converted into lipids. Figure 1.
It is used universally as an energy storage form in all energy-dependent cellular processes. It is not a "general storage form" of energy for eventual use but is produced and consumed in a continuous cycle whose velocity is matched to the prevailing rate of cellular processes, including those of syntheses, membrane-bound ion pumps,
