(a)
Interpretation:
Whether the statement “about 50% of TAGs undergo complete hydrolysis in the stomach” concerning to triacylglycerol(TAG) digestion is true or false has to be determined.
Concept introduction:
Triacylglycerols are lipid molecules which constitute around 98% of the total dietary lipids. These lipid molecules undergo digestion/breakdown into simpler forms in the
(b)
Interpretation:
Whether the statement “cholecystokinin is the chemical name for bile” concerning to triacylglycerol(TAG) digestion is true or false has to be determined.
Concept introduction:
Triacylglycerols are lipid molecules which constitute around 98% of the total dietary lipids. These lipid molecules undergo digestion/breakdown into simpler forms in the digestive system and are later absorbed into the bloodstream. In the bloodstream, the hydrolysis products of triacylglycerols (fatty acids and glycerol) are absorbed by the body cells and are either broken down into acetyl CoA or stored as lipids for future use. Fats/Lipids are a richer source of energy compared to carbohydrates. While carbohydrates provide energy for immediate use, lipids provide energy for long term or future use. The structure of triacylglycerols is as follows:
(c)
Interpretation:
Whether the statement “most TAGs usually enter the small intestine in the form of monoacylglycerols” concerning to triacylglycerol(TAG) digestion is true or false has to be determined.

Interpretation:
Whether the statement “chyme produced in the stomach settles to the bottom of the stomach” concerning to triacylglycerol(TAG) digestion is true or false has to be determined.

- Quantum mechanics. Explain the basis of approximating the summation to an integral in translational motion.arrow_forwardQuantum mechanics. In translational motion, the summation is replaced by an integral when evaluating the partition function. This is correct becausea) the spacing of the translational energy levels is very small compared to the product kTb) the spacing of the translational energy levels is comparable to the product kTc) the spacing of the translational energy levels is very large compared to the product kTarrow_forwardDon't used Ai solutionarrow_forward
