Chemistry and metabolism - COMPLETE Flashcards
(23 cards)
Define and Describe pH
Measure of acidity in a substance.
Define and Describe acid
Chemical that gives of Hydrogen ions
Define and Describe Base
A molecule that can accept proteins and donate electrons
Define and Describe Buffer
When acidic or basic components are added it can resist a change in pH
Define cellular respiration
Metabolic pathway that breaks down glucose and produces ATP
Equation for cellular respiration
C^6H^12O^6 + 6O^2 —–> 6CO^2 +6H^2 O
What is Glycolysis?
Splitting of glucose into two pyruvate molecules
Energy Input in Glycolysis
Uses a small amount
Oxygen Use in Glycolysis
Does not require oxygen
Byproduct in Glycolysis
Two pyruvate and 2 ATP
Cellular Location in Glycolysis
In the cytoplasm
What is the Krebs Cycle?
A series of reactions that release stored energy
Energy Input in The Krebs cycle
Two pyruvate
Oxygen Use in The Krebs cycle
No oxygen is used
Byproducts of The Krebs cycle
NADH, FADH
Cellular location of The Krebs cycle
Mitochondria
Energy input in the electron transport chain
Hydrogen ions and ATP
What is the Electron Transport Chain?
A series of hydrogen ions in the outer ring of the mitochondria that create a membrane potential that produces energy
Oxygen use in the electron transport chain
Oxygen binds to the hydrogen molecules that have been spun out of the mitochondria membrane to get rid of them
Byproducts of the electron transport chain
H^2O molecules. ATP
Cellular Location of the electron transport chain
Mitochondria
Energy efficiency of the Glucose to ATP energy producion
92% effective. Requires little energy
Difference Between Anaerobic and Aerobic Respiration
Anaerobic does not oxygen. Aerobic uses oxygen
