Flashcards in  Class 5- Theisen Fundametal Of Nutrition Deck (141)
What is req'd for coagulation in gamma carboxylase rxn ?
Vit K hydroquinione (active)
Why do energy drinks and vitamins boost energy?
They provide substances that fit into TCA cycle- increase action of cellular respiration
Req'd minerals in diet:
Ca+, P, Mag, Fe, S mineral
I,Se,Cu,Zn. Trace mineral
Mn,F,Cr, Mo ultratrace mineral
Why do low vitamins/minerals affect activity?
Theyre req'd for certain molecular processes by the proteins/enzymes that complete the processes
Small organic molecules often derived from vitamins, what're they called when tightly bound?
Coenzymes ; prosthetic groups
Oxidation state of Fe when being transported in circulation:
3+, b/c it wants to be unrecognizable and not uptaken by any tissue/cell until destination is found
Oxidation state of Fe when entering in cell/tissue from circulation:
2+, this is recognizable for cells/tissues
Transport molecule for Fe
Specific Fe pore:
In order to enter cell Fe3+ must become Fe2+. This occurs by what enzyme? What vitamin is req'd for this enzyme to function?
Energy req'd to maintain life:
basal metabolic rate (BMR)
A linked series of chemical reacitons that begins w/ a particular molecule and converts it into some other molecules or molecules in a carefully defined fashion
Which enzymes predominant in the interdependent metabolism pathways coordinated by sensitive means of communication?
Those that convert energy from fuels into biologically useful forms
Those that req' inputs of energy tp proceed
Universal currency of free energy
Which bond of ATP is most labile
What is the significance of ATP ?
High energy bonds
An important form of cellular energy transformation
Serves as the principal immediate donor of free energy

Strenuous exertion of ATP may be as high as ____kg/min
Important source of cellular energy
Oxidation of carbon fuels
Having mechanisms for regeneration of ATP=
Activities that req' ATP:
Motion, active transport, signal amplification, and biosynthesis
One of the primary roles of catabolism
Generation of ATP
