How can metabolism be defined -correct answer_As the sum of all the chemical runs that take
place in an organism What are characteristics of anabolism -correct answer_small molecules
-> larger molecule Make bonds Require energy (endothermic, Change in H = +) what are
characteristics of catabolism -correct answer_Large molecules -> small molecules Break
bonds Release energy ( exothermic, change in H = -) What are the 2 kinds of pathways in
metabolism -correct answer_linear and cyclic What happens in the last step of cyclic pathways
-correct answer_The last step regenerates the compound that started the cycle What are the 4
stages of metabolism in order -correct answer_1- Digestion 2- Produce Acetyl-CoA 3- Citric
Acid Cycle 4- Electron Transport chain and Oxidative phosphorylation What is the physical
component in stage 1 -correct answer_Grinding food ( mouth and stomach) What is the
chemical component in stage 1 -correct answer_Hydrolysis What is the production goal of
stage 3 -correct answer_NADH & FADH2 What is the production goal of stage 4 -correct
answer_ATP What does ATP stand for -correct answer_Adenosine 5'-triphosphate What does
ADP stand for -correct answer_Adenosine 5'-diphosphate What is the energy carrying
molecule -correct answer_ATP What is the delta H in ATP hydrolysizing to ADP -correct
answer_-7.3 kcal/mol is ATP hydrolysizing to ADP endothermic or exothermic? Does it require
energy or release energy? -correct answer_Exothermic Releases energy What is a coupling
reaction -correct answer_When ATP hydrolysis supplies the energy to the unfavorable
process/ rxn ( the one w/ a positive delta H) coenzymes -correct answer_can be oxidizing or
reducing agents oxidation -correct answer_loses e- or H+ reduction -correct answer_gains e-
or H+ What is the name of NaD+ -correct answer_nicotinamide adenine dinucleotide Is NaD+
a reducing agent or oxidizing agent -correct answer_oxidizing agent What is the name of
NaDH -correct answer_nicotinamide adenine dinucleotide (reduced form) Is NaDH a reducing
agent or oxidizing agent -correct answer_reducing agent where does glycolysis occur -correct
answer_in the cytosol is glycolysis aerobic or anaerobic -correct answer_anaerobic what is the
pathway for glycolysis -correct answer_it is a 10 step linear pathway what are steps 1-5 called
-correct answer_The energy investment phase what are steps 6-10 called -correct answer_the
energy generating phase what goes into the energy investment phase -correct answer_1
glucose & 2 ATP what comes out of the energy investment phase -correct answer_2
glyceraldehyde 3-phosphate & 2 ADP what goes into the energy generating phase -correct
answer_2 glyceraldehyde 3-phosphate & 2 NAD+ & 4 ADP what comes out of the energy
generating phase -correct answer_2 pyruvate & 2 NADH + 2H+ & 4 ATP what are the overall
products and reactants of glyclolysis -correct answer_1 glucose & 2 ADP & 2 NAD+ ---> 2
pyruvate & 2 ATP & 2 NADH + 2 H+ what is an aerobic pyruvate -correct answer_is is rich in
O2, has plenty of NAD+ what is an anaerobic pyruvate -correct answer_It is O2 poor, has little
NAD+ but plenty NADH what does an anaerobic pyrite produce -correct answer_lactate where
does lactate move -correct answer_from the muscles to the liver do H+ pump with or against
the concentration gradient -correct answer_against (active transport) where does the energy
