Chapter 25 Metablosim Flashcards
Sum total or all biochemical reactions in our bodies
Metabolism
Building up with reactions, convert small molecules into longer molecules
Anabolism
Digestion degradable breaks down smaller molecules into smaller ones
Catabolism
Is any substance that increases the rate of a chemical reaction
Catalyst
Any substance that increases the rate of a biological reaction
Enzymes
Any substance acted upon by an enzyme
Substrate
Region or area on an enzyme where the enzyme activity takes place
Active site
Occurs in the cytosol of the cell
Nets 2 molecules of atp
Converts a molecule of glucose into 2 molecules of pyruvic acid
Provides hydrogen ions to electron carriers for ets in the form of 2 NADH molecules
Glycolysis
Occurs in mitochondrial matrix
Produces 2 atp
Provides hydrogen ions for electron Carriers for ets in the form of nadh and Fadh molecules
Produces carbon dioxide wastes
TCA cycle Krebs or citric acid cycle
Occurs at enzymes in mitochondrial cristae
Produces 32 ATP
Consumes oxygen to form water with H+ from nadh and fadh2 from glycolysis and TCA
Electron transport system ETS or ET chain
Occurs in cytoplasm
Glycolysis
When pyruvate enters the matrix of the mitochondria it converts to ?
Acetyl-COA
Removal of proteins of an amino group
Deamination
Urine smells like
Ammonia
Folds inside of the mitochondria?
Cristae
The molecules that are imbedded in the cristae of the mitochondria
Cytochromes
Where in the cell does glycolysis occur ?
Cytoplasm
How much energy is netted during glycolysis
2 ATP and 2 NADH
What is the function of NAD+ in glycolysis?
Electron carrier
What molecule is glucose broken down to by the end of glycolysis?
Pyruvate
Where in the cell does the TCA occur
Mitochondria matrix
What molecule from glycolysis is used in TCA ?
Pyruvate
What are the electron carriers for TCA ?
NADH and fadh2
How much ATP is produced in one turn of the TCA cycle
1
How many times must the TCA turn to burn all the products of glycolysis?
2
What waste molecule is produced by the TCA cycle ?
Carbon dioxide
Where in the cell does the ETS occur ?
Mitochondria
What do glycolysis and TCA provide for ets
NADH and fadh2
How many ATP molecules are formed in the ETS?
30-32
What molecule is produced by H+ and o2 at the end of the ETS?
Water
