Also called redox reaction
Oxidation is the removal of electrons from an atom or molecule, which will produce energy and reduction is the gaining of electrons
NADH is the oxidized form while NAD+ is the reduced form
Glucose is a reduced molecule
True
False
They interact with another part of the enzyme, called allosteric site
This binding will change the shape of the active site, making it nonfunctional
The enzyme activity remains the same all in all
Depending of the ability of the active site to return to its original shape, it can be either reversible or irreversible
Competitive and noncompetitive inhibitors
PH: enzyme activity declines when above or below optimum pH of most enzymes
Temperature: rate of reaction declines beyond the optimal temperature because the enzyme loses its characteristics (tertiary configuration), called denaturation
Enzymatic activity increases as substrate concentration increases until the enzymes are saturated
Catabolism refers to chemical reactions that result in the breakdown of more complex organic molecules into simple substances.
Catabolic and anabolic reactions usually require energy
Anabolism refers to chemical reactions in which complex substances are combined together to form even more complex molecules
The energy for chemical reactions is stored in ATP
Metabolism is the bigger category that is divided in chemical reactions that release energy and chemical reactions that require energy
A, B, and C are correct
A, D, and E are correct
B and C are correct
None is correct
All is correct
ATP stores energy derived from catabolic reactions and releases it later to drive anabolic reactions and perform other cellular work
Catabolic reactions transfer energy from complex molecules to ATP such as glucose, starch and lipids
Anabolic reactions transfer energy from ATP to complex molecules such as glycerol, fatty acids and proteins
When the terminal phosphate group is split from ATP, adenosine diphosphate (ADP) is formed, and energy is released to drive anabolic reactions
They are specific
Catalysts are substances that can speed up a chemical reaction without being permanently altered themselves. Enzymes serve as biological catalysts.
Have an active site
The enzyme-substrate complex formed by the temporary binding of enzymes and reactants enables the collisions to be more efective and increases the activation energy of the reaction.
6 NADH
2 Pyruvates
4 CO2
Acetyl CoA
2 Guanosine diphosphate (GDP)
2 FADH2
2 FAD
2 Guanosine triphosphate (GTP)
6 NAD+
2 Adenosine triphosphate (ATP)
2 H2O
2 adenosine diphosphate (ADP)
2 NADH
2 Pyruvic acids
2 NAD+
Fermentation can be either aerobic or anaerobic. It releases energy from sugars or other organic molecules by oxidation.
Fermentation requires O2
NAD+ is being reduced in fermentation, glycolysis and Krebs cycle
Aerobic respiration consists of the Krebs Cycle, the Electron Transport Chain (system) and chemiosmosis
The final electron acceptor in aerobic respiration is an inorganic molecule other than O2 or, rarely, an organic molecule
Glycolysis is an aerobic pathway for the oxidation of glucose
The total ATP yield is less than in aerobic respiration because only part of the Krebs cycle operates under anaerobic conditions
B, E, and F are false
B, C, E and G are false
All is true
All is false
Pentose phosphate pathway
Calvin-Benson cycle
Krebs cycle
Entner-Doudoroff pathway
Embden-Meyerhof pathway
True
False
Lipases break down fat into its fatty acids and glycerol components
Proteases and peptidases break down proteins into amino acids
Transamination, decarboxylation and dehydrogenation reactions convert the amino acids to be catabolized
A and B are false
All is false
None is false
True, so easy man.
False, never ready for that.
Wait!
