Question

lipids are a diverse group of biological macromolecules that include triglycerides, phospholipids, waxes, and steroids. the structure of each type of lipid impacts its function. determine whether each statement is true or false. a gram of protein supplies more energy than a gram of fat. the structure of a lipid impacts its properties. lipids are mostly hydrophobic. (chart with true and false columns for each statement)

Explanation:

For the statement "A gram of protein supplies more energy than a gram of fat":

• Explanation: Fats (lipids) provide more energy per gram (about 9 kcal/g) than proteins (about 4 kcal/g). So this statement is false.

For the statement "The structure of a lipid impacts its properties":

• Explanation: The structure - function relationship is a key concept in biology. Different lipid structures (e.g., triglycerides vs phospholipids) lead to different properties (e.g., energy storage vs cell membrane structure). So this statement is true.

For the statement "Lipids are mostly hydrophobic":

• Explanation: Lipids are largely non - polar, and non - polar molecules are hydrophobic (repel water). For example, fats and oils do not dissolve in water. So this statement is true.

Answer:

s for each statement:

• "A gram of protein supplies more energy than a gram of fat": False
• "The structure of a lipid impacts its properties": True
• "Lipids are mostly hydrophobic": True
