complete the following chart in class.
chart columns: macromolecule, molecular make - up, structure, monomer (building block), function, example (with kit - kat and cellulose written)

Answer:

To solve these questions, we analyze the role of each macromolecule:

Question 5 (Quick energy boost)

• Explanation: Monosaccharides (e.g., glucose) are simple sugars, the fastest - acting energy source as they are quickly broken down. A Kit - Kat has monosaccharides (from sugars) and other macromolecules, but for a quick boost, monosaccharide - rich foods (or foods with easily digestible carbs like Kit - Kat’s sugar) work.
• Answer: A Kit - Kat (or foods with monosaccharides/polysaccharides broken down quickly, but monosaccharides give the quickest boost; Kit - Kat has sugars that are monosaccharide - derived or simple carbs).

Question 6 (Strong nails)

• Explanation: Nails are made of keratin (a protein). Proteins are for structural support. So foods rich in protein (e.g., if Kit - Kat had protein, but generally protein - rich foods; however, the example uses Kit - Kat, maybe the context is about macromolecules, and protein is the key for nail growth as keratin is a protein).
• Answer: Foods rich in protein (if Kit - Kat is considered, maybe its protein content, but generally protein - based foods as protein is the building block of nails).

Question 7 (Haven’t eaten in days)

• Explanation: Lipids (fats) are long - term energy storage. After carbs are used, lipids are mobilized. Also, proteins can be used in extreme cases, but lipids are the main reserve. So foods with lipids (or a balanced meal, but lipids for long - term energy).
• Answer: Foods rich in lipids (or a meal with lipids, carbs, and protein; but lipids are key for long - term energy when starved).

Question 8 (Healthy hair)

• Explanation: Hair is made of keratin (protein). So protein - rich foods are needed for hair growth as protein is the structural component.
• Answer: Foods rich in protein (e.g., meat, eggs; if Kit - Kat is considered, its protein content, but protein - based foods are best).

Question 9 (Race tomorrow afternoon)

• Explanation: Polysaccharides (e.g., glycogen from carbs like in Kit - Kat’s carbs) are stored energy, broken down to glucose for sustained energy during exercise. So a meal with polysaccharides (or carbs) for energy storage to use during the race.
• Answer: Foods with polysaccharides (e.g., Kit - Kat has carbs that are polysaccharides or broken down to them, providing energy for the race).

Question 10 (Getting ready for hibernation)

• Explanation: Hibernation requires long - term energy storage, so lipids (fats) are ideal as they store the most energy per gram. So foods rich in lipids to build up fat reserves.
• Answer: Foods rich in lipids (to store energy for hibernation).

Question 11 (Bigger muscles)

• Explanation: Muscles are made of protein (actin, myosin). To build muscle, protein is needed for synthesis, along with exercise. So protein - rich foods.
• Answer: Foods rich in protein (for muscle synthesis).

Question 12 (Next meal in a week)

• Explanation: Need long - term energy storage, so lipids (fats) and proteins (for maintenance) and carbs. But lipids are best for long - term energy. So a meal rich in lipids and protein to sustain for a week.
• Answer: A meal rich in lipids and protein (to store energy and maintain body functions).

Question 13 (Monomers linked and disassembled)

• Explanation: Macromolecules are polymers of monomers:
• Carbohydrates: Monomers (monosaccharides) linked by glycosidic bonds, disassembled by hydrolysis (adding water to break bonds).
• Proteins: Monomers (amino acids) linked by peptide bonds, disassembled by hydrolysis.
• Lipids: Not true polymers, but fatty acids and glycerol; disassembled by hydrolysis.
• Nucleic Acids: Monomers (nucleotides) linked by phosphodiester bonds, disassembled by hydrolysis.
• In summary, monomers are linked via dehydration synthesis (removing water to form bonds) and disassembled via hydrolysis (adding water to break bonds).
• Answer: Macromolecule monomers (e.g., monosaccharides for carbs, amino acids for proteins) are linked by dehydration synthesis (losing water to form covalent bonds like glycosidic/peptide bonds) and disassembled by hydrolysis (adding water to break those bonds).

Question 14 (Macromolecule properties chart)

Assuming the chart has columns: Macromolecule, Molecular make - up, Structure, Monomer, Function, Example (Kit - Kat has carbs, lipids, protein):

Macromolecule	Molecular make - up	Structure	Monomer	Function	Example (Kit - Kat)
Lipids	C, H, O (more H, less O)	Non - polar, fat droplets/membranes	Fatty acids + glycerol	Energy storage, insulation	Fats, oils (Kit - Kat’s fat)
Proteins	C, H, O, N (sometimes S)	Amino acid chains (primary - quaternary)	Amino acid	Structure, enzymes, transport	Keratin, enzymes (Kit - Kat’s protein)

(Note: For each question, the key is identifying the macromolecule’s role: carbs for quick energy, protein for structure/growth, lipids for long - term energy.)
