Terms in this set (25)
What are most foods used as?
What is energy value of food measured in
kilocalories or calories
substance used by the body for growth, maintenance, and repair
what are some major nutrients?
carbohydrates, lipids, proteins, water
what are some minor nutrients
vitamins and minerals
What are the 5 food groups?
grains, fruits, vegetables, protein, dairy
sugars and starches derived from plants
saturated fats from animal products, unsaturated fats from oils/nuts, cholesterol from egg yolk and milk products
contain all essential amino acids (most are from animal products)
essential amino acids
body cannot make but must be obtained through diet
Legumes and beans
found mainly in fruits and vegetables that function as coenzymes
foods richest in minerals
vegetables, legumes, milk and come meats
All of the chemical reactions that are needed to maintain life
substances are broken down to simpler substances, and energy is released and captured to make ATP
larger molecules are built from smaller ones
What are broken down to make ATP?
fuel used to make ATP; blood sugar
as glucose is oxidized, carbon dioxide, water and ATP are formed (C6H12O6 + 6 O2 = 6 CO2 + 6 H2O + ATP)
What are the events of three main metabolic pathways of cellular respiration?
Glycolysis, citric acid cycle (krebs cycle), and electron transport chain
occurs in cytosol, and energizes a glucose molecule so it can be split into two pyruvic acid molecules and yield ATP
in mitochondria; produces CO2 and water resulting from cellular respiration and yields a small amount of atp
electron transport chain
hydrogen atoms removed during glycolysis and the citric acid cycle are delivered to protein carriers; H atoms are split into hydrogen ions and electrons in the mitochondria; production of ATP from electrons giving off energy
high blood sugar; excess glucose levels
low level of glucose in the blood
