BIO 1500 chapter 21
1. What must an animal diet provide?: •Chemical energy (stored within chemical bonds) needed for
cellular processes
• Building blocks (organic precursors) for macromolecules
• Essential nutrients
2. At the cellular level, molecules necessary for animal function: (4): amino acids,
simple sugars, lipid molecules, and nucleotides
3. Crucial to maintain a balance between food intake, storage, and energy
expenditure (TRUE OR FALSE): TRUE
4. Intake in more than necessary amounts is stored as in liver,
and in muscle and fat cells: glycogen
5. DIET
- Source of materials needed for (energy) production in cells
,- Source of materials needed for biosynthesis of and other complex
molecules needed for growth, maintenance, and reproduction
- Must be balanced to provide and required
for cellular function: ATP, DNA, minerals, vitamins
6. Organic precursors/molecules required for building cellular material and
tissues must come from : food
7. Primary components of food:: complex carbohydrates, proteins, and fats.
8. Animals do not convert these macromolecules into simple molecules, they
are able to consume them right away unlike plants (TRUE OR FALSE): FALSE: Animals
must convert these macromolecules into simple molecules required for cellular functions
9. PRIMARY COMPONENTS OF FOOD:
,Carbohydrates/sugars: primary source of organic
- breakdown into by catabolism; source of energy (ATP)
Protein: source of organic
- catabolism provides used for cellular function.
- and derived from these become the building block
, for nucleotides, nucleic acids, proteins, cells, and tissues
Fatty foods: also, significant sources of energy (one gram of fat contains 9
calories)
- Fats aid the absorption of fat-soluble and
production: - carbons, glucose
- nitrogen, amino acids, carbon, nitrogen
- vitamins , hormones
10. Required materials that an animal cannot assemble from simpler organic
molecules;
- Must be obtained from
Include:
1. Some essential
