HBIO 202 Rev Exam Questions With 100%
Verified Answers!!
Nutrients
chemical compounds in foods to provide fuel for energy, growth, and maintenance, and to
regulate body processes
kilocalories
Metabolism
Nutrition
the science that studies how nutrients and compounds in foods nourish and affect body functions
and health
Macronutrients
energy-yielding nutrients needed in higher amounts
* Carbohydrates, lipids (fats), and proteins
* Organic compounds (contain carbon)
Micronutrients
needed in small amounts and together are essential for physiological functions (we cannot create
them)
* vitamins and minerals
*Vitamins are Organic (contain Carbon) -- minerals are inorganic
Carbohydrates
The major source of energy for our body
* organic molecules = they contain carbon
Lipids
, organic molecules that serve as structure for membranes, signal for hormones, energy for fuel,
for insulation and protection, and are also a solvent
Proteins
organic molecules that are used for/as:
* movement (microfilaments)
* Enzymes (Lactate dehydrogenase)
* Structure (Keratin)
* Hormones (Insulin)
*Defense (Antibodies)
* Transport (Hemoglobin)
Vitamins
Organic micronutrients with diverse biological functions
*Work as hormones (Vit D)
*Co-Enzymes (Vit B2, B3)
*Antioxidants (Vit C, Vit E)
Minerals
Inorganic micronutrients with diverse biological functions
*Co-Factors (Magnesium, Phosphorus)
*Structure (Calcium, Phosphorus)
*Signaling (calcium)
Six classes of nutrients
* Carbohydrates, fats, proteins : provide energy in the form of Kilocalories
* Vitamins, minerals, water: help regulate many body processes, including metabolism
Water
Vital for many processes in your body
* part of fluid medium inside and outside of cells
* helps chemical reactions
