Cellular Respiration (5.3) Flashcards
Outline the positioning of glycolysis in aerobic respiration
First biochemical pathway
State what the energy released from glucose in cellular respiration is used to generate
ATP
State how the energy from ATP is transferred
When the high energy bond of ATP breaks to form ADP and phosphate
Provide the chemical formula for the release of energy from ATP
ADP + Pi -> ADP ~ Pi (ATP)
Describe what the squiggly line in ADP ~ Pi represents
High energy bond
State what ATP can be used by a cell for
Vital cellular processes including protein synthesis and active transport
State what aerobic cellular respiration requires
Oxygen
State the 3 interconnected biochemical pathways of aerobic cellular respiration
- glycolysis
- Krebs cycle
- electron transport chain
State where glycolysis occurs
Cell cytosol
State what molecule is broken down during glycolysis and what it is broken into
Glucose is broken down into pyruvate
State what the two three-carbon molecules glucose is broken down into during glycolysis should be referred to as
Pyruvate
State whether or not energy is released during glycolysis and if so, how much
2ATP of energy is released
State where the released energy of glycolysis is transferred to during aerobic respiration
Coenzymes ATP and NADPH
Describe the individual chemical inputs of glycolysis for aerobic respiration
C6H12O6, ADP + Pi and NAD+
Describe the individual chemical outputs of glycolysis for aerobic respiration
C3H4O3 (pyruvate), ATP and NADPH
Describe pyruvate
Three carbon molecules formed during the glycolysis stage of aerobic cellular respiration
Describe high energy bonds
Electrons of the bonds are in a high energy state. The bonds themselves are relatively weak, requiring a small amount of energy to break.
Describe oxidation
Reaction in which a substance is combined with oxygen
Describe redox reaction
Chemical reaction that involves a transfer of electrons between two species
Describe phosphorylation
Biochemical process that involves the addition of phosphate to an organic compound.
Describe aerobic respiration
Respiration requiring oxygen as the terminal electron acceptor
Describe alcoholic fermentation
Anaerobic pathway where ethanal acts as the electron acceptor forming ethanol as the product
Describe the electron transport chain
Enzyme-based redox reaction which pass electrons from high to low redox potentials
Describe glycolysis
Series of reactions the convert glucose to pyruvate
Describe lactic acid fermentation
Anaerobic pathway where pyruvate is reduced to lactic acid
