CORRECT WELL DETAILED ANSWERS GRADED A+ SCORE
SOLUTION
In the bloodstream, monoglycerides are hydrolyzed to ___ and
___ by ___ of capillary endothelium.
Free fatty acids, glycerol, lipoprotein lipase
What are the 4 types of transport lipoproteins?
1. Chylomicrons (lowest density, transport lipids to adipose,
cardiac, and skeletal muscle)
2. Vldls (very low density, transport triglycerides from liver to
peripheral tissues)
3. Ldls (low density, transport cholesterol to to peripheral
tissues)
4. Hdls (high density, transport excess cholesterol from
peripheral tissues to liver to be broken down into bile)
High hdl (>60 mg/dl) is ___, while high ldl (>130 mg/dl) is ___.
Healthy, unhealthy
Nucleic acid bases are taken up by
Secondary active transport (with na+)
,Nucleic acid phosphates are taken up by
Na+ costrasporters in the apical membrane, or facilitated
diffusion in the basolateral membrane
Iron is absorbed mostly in the duodenum. It is stored in
mucosal cells using ___, and when needed, it is transported in
blood by ___
Ferritin, transferrin
Calcium is absorbed mostly by the duodenum. It is absorbed by
channels regulated by ___ and ___
Vitamin d, parathyroid hormone
Na+ enters through channels and is coupled with active
absorption of ___ and ___
Glucose, amino acids
Cl- enters through secondary active transport with ___ in and
___ out)
Na+, hco3-
, K+ enters through a paracellular route (between cells) along
with ___
Water
Water is mostly absorbed in the ___ and a little in the ___, both
through osmosis
Small intestine and large intestine
Carbohydrates are mostly converted into ___
Atp (energy)
Fats are mostly converted to ___ for storage, but can later be
used to as an energy source to make atp
Triglycerides
Proteins are mostly used in amino acid synthesis, but excess
are modified and used for ___ or stored as fat in the ___
Atp synthesis, liver
What absorption happens in the large intestine?
Very little. Some water, ions, and a few vitamins.
