Aperçu du contenu
Carbohydrates SGGlucose is not the only substrate that is catabolized in cellular respiration? However, the catabolization
of glucose is always used as an example to explain the process of cellular respiration. Glucose is used as
an example because of the important role it plays in animal energy metabolism, why is it so important,
why is it used as an example as opposed to other types of substrates? - correct answer ✔✔Readily
available energy source, We use this energy source to make ATP. ATP has a short shelf life. Glucose is
stable and can be kept in our cells to make ATP. Cellular communication and gene regulation, Supports
healthy digestive system and cardiovascular system, the overall health in animals.
On several occasions in class we have referenced both cellular respiration and anaerobic fermentation,
on a physiological level what is the defining factor that sets these two processes apart? - correct answer
✔✔oxygen.
What elements are carbohydrates composed of? - correct answer ✔✔carbon, hydrogen, oxygen
What is a biochemists definition of a carbohydrate? - correct answer ✔✔Having 3 carbons
Identify the general roles of carbohydrates in the physiology of animals. - correct answer ✔✔readily
available source of energy
energy storage
cellular communication
supports healthy
digestion system
cardiovascular system
Through what process does carbon transition from an inorganic to an organic state, what are the
inorganic and organic forms? - correct answer ✔✔photosynthesis,
primary production, carbon fixation.
, Explain the difference between mono-, di-, oligo-, and poly- saccharides. - correct answer ✔✔Mono- 1
Di- These are sugars.
Oligo- 3-10
Poly- more than 10 sugars.
Oligo saccharides - correct answer ✔✔3-10 monosaccharides
polysaccharides - correct answer ✔✔over 10
Explain how monosaccharides are classified by the following properties: number of carbons, location of
carbonyl group, and chirality. - correct answer ✔✔Number of carbons, trio, pentose, hextose, -Every
sugar has a carbonyl functional
Group. The location of this matters. When the carbonyl functional groups are on the end they are an
aldehyde and if they are located in the middle they are ketones and the isomeric configuration.
They have the same molecular formula but a different structure.
what happens if the carbonyl function is located on the end - correct answer ✔✔it is an aldehyde
(aldoses)
What happens if the carbonyl group is located in the middle - correct answer ✔✔it's a ketone (ketose for
sugar)
How does the chemical reactions dehydration synthesis and hydrolysis apply to carbohydrates? - correct
answer ✔✔This dehydration synthesis is how you get a disaccharide.
You take the OH and the H and form water and this causes a covalent bond and creates a disaccharide.
There is also different glycosidic linkage depending on which carbons they interact with.
Explain the difference between an alpha bond and a beta bond. - correct answer ✔✔Alpha glucose is
used for glycogen and starch
beta is used for cellulose and this creates more hydrogen bonds that causes the strength of the structure
this is why we can't break it down.
