Question

1. what macronutrient building block serves as the brains primary energy source?

○ glucose
○ amino acids
○ fatty acids
○ triglycerides

1. what nutrient helps with creating brain cell membranes?

○ omega-3 fatty acids
○ fiber
○ glucose

Explanation:

Question 3

The brain's primary energy source is glucose. Glucose is a simple sugar (a monosaccharide) that is the main fuel for brain cells. Amino acids are building blocks of proteins, fatty acids are components of fats, and triglycerides are storage forms of fat—none of these are the primary energy source for the brain.

Omega - 3 fatty acids are a type of fat that is important for the structure of brain cell membranes. Fiber is a type of carbohydrate that aids in digestion, glucose is a sugar (energy source), and while other fats are important, omega - 3s have a key role in brain cell membrane formation.

Answer:

Glucose
