91

What is req'd for coagulation in gamma carboxylase rxn ?

CO2
O2
Vit K hydroquinione (active)

92

Why do energy drinks and vitamins boost energy?

They provide substances that fit into TCA cycle- increase action of cellular respiration

93

Req'd minerals in diet:

Na+,K+,Cl- electrolyte
Ca+, P, Mag, Fe, S mineral
I,Se,Cu,Zn. Trace mineral
Mn,F,Cr, Mo ultratrace mineral

94

Why do low vitamins/minerals affect activity?

Theyre req'd for certain molecular processes by the proteins/enzymes that complete the processes

95

Small organic molecules often derived from vitamins, what're they called when tightly bound?

Coenzymes ; prosthetic groups

96

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

97

Oxidation state of Fe when entering in cell/tissue from circulation:

2+, this is recognizable for cells/tissues

98

Transport molecule for Fe

Transferrin q

99

Specific Fe pore:

Ferroportin

100

In order to enter cell Fe3+ must become Fe2+. This occurs by what enzyme? What vitamin is req'd for this enzyme to function?

Ferric reductase;
Vitamin C

101

Energy req'd to maintain life:

basal metabolic rate (BMR)

102

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

Metabolism

103

Which enzymes predominant in the interdependent metabolism pathways coordinated by sensitive means of communication?

Allosteric

104

Those that convert energy from fuels into biologically useful forms

Catabolic

105

Those that req' inputs of energy tp proceed

Anabolic

106

Universal currency of free energy

ATP

107

Which bond of ATP is most labile

Gamma

108

What is the significance of ATP ?

High energy bonds

109

An important form of cellular energy transformation

Phosphoryl-transfer potential

110

Serves as the principal immediate donor of free energy

ATP

111

Total quantity of ATP in the body is limited to

100 g

113

Turnover of small ATP quantity [100 g]:

Is very high

114

Human ATP consumption in 24 hours

40 kg

115

Strenuous exertion of ATP may be as high as ____kg/min

0.5

116

Important source of cellular energy

Oxidation of carbon fuels

117

Having mechanisms for regeneration of ATP=

Vital

118

Activities that req' ATP:

Motion, active transport, signal amplification, and biosynthesis

119

One of the primary roles of catabolism

Generation of ATP

120

Fuel molecules composed of carbon are oxidized to

CO2, resulting e-are captured and used to regenerate ATP from ADP
