What happens to nutrients after digestion and absorption? - ANSWER blood vessel collect nutrient-rich
blood from the digestive organs and delivers them to the liver
lymphatic system: three principle functions - ANSWER 1. collect and return interstitial fluid, including
plasma protein to the blood
2. to defened the body against disease by producing lymphotcytes and cleansing body fluids
3. to absorb lipids from the intestine and transport them to the blood
final destination of nutrients: the cell - ANSWER blood carries nutrients to the cells, nutrients cross cell
membranes -->
inside the cell, nutrietnts are used for energy or to build substances for the body
mitochondria - ANSWER produces ATP
ribosomes - ANSWER makes protein
metabolic reactions - ANSWER series of chemical reactions inside an organism; may require coenzymes;
results in the transformation of one molecule to another
anabolism - ANSWER smaller molecules combine to form complex structures
catabolism - ANSWER breaking down substances for energy
cellular respiration: how ATP is produced - ANSWER carbs --> glucose
,NUSC 1165 exam 2 (chea) 221 complete
solutions.
proteins --> amino acids
lipids --> fatty acids
acetyl coA is then metabolized in the citric acid cycle and electron transport
overall end product: CO2, water, ATP
what are the overall end products of cellular respiration? - ANSWER CO2, water, ATP
what is the storage form of carbs in muscles? - ANSWER glycogen
what is the storage form of fat? - ANSWER triglycerides
how are substances that are unable to be absorbed by the body excreted? - ANSWER things such as
fiber, is excreted via GI tract in feces
what are the organs that have a role in eliminating metabolic waste? - ANSWER lungs, kidneys, skin
products eliminated from lungs and skin - ANSWER CO2 and water
products eliminated from urinary system - ANSWER water, "waste products"
kidneys - ANSWER part of the urinary system and is the primary site where excess water, metabolic
waste products and minerals are excreted
nephrons - ANSWER functional unit; filters blood and maintains fluid balance
glomerulus - ANSWER ball of capillaries located within the nephron; filters blood during urine formation

solutions.
reabsorption of filtered substances back in the blood can also occur if they are needed
refined carbs - ANSWER food that went through processing
unrefined carbs - ANSWER natural state, not processed
empty calories - ANSWER calories derived from food containing no nutrients
simple carbs - ANSWER monosaccharides and disaccharides
complex carbs - ANSWER oligosaccharides, glycogen, starch and fiber
glucose (blood sugar) - ANSWER main provider of energy for body; produced by plants during
photosynthesis
fodos: component of disaccharide or starch
galactose - ANSWER component of lactose
fructose - ANSWER fruit sugar; fruits, veggies, honey
high fructose corn syrup
photosynthesis - ANSWER process of converting CO2 and water to glucose using energy directly from
the sun
maltose - ANSWER glucose and glucose
solutions.
