Presentation Transcript
Respiration :Respiration
Respiration :Respiration Glucose (6C) Pyruvic Acid (3C) Acetyl CoA (2C) ADP +Pi ATP NAD NADH NAD NADH CO2 GLYCOLYSIS:
Occurs in the Cytoplasm
Does not require oxygen (Anaerobic)
Need 2 ATP to start
Net gain of 2 ATP Citric Acid (6C) (4C) compound CO2 NAD NADH KREBS CYCLE:
Occurs in the Central matrix of the Mitochondria.
Requires Oxygen (Aerobic)
A series of Enzymes produce Citric acid. NADH ATP ATP CYTOCHROME SYSTEM:
Transfers Hydrogen into ATP
38 ATP molecules are made
NADH from other stages passed to here
Requires Oxygen. O2 H2O
Alternate substrates :Alternate substrates Other than CARBOYDRATES (glucose),
FATS
PROTEINS
NUCLEIC ACIDS
Can all be substrates during respiration
Anaerobic Respiration of Glucose :Anaerobic Respiration of Glucose In the absence of Oxygen:
There is no NADH
Hydrogen cannot pass through to the Cytochrome system
Cytochrome system and Krebs Cycle cannot take place
Only 2 ATP produced
Pyruvic Acid can only be broken down further anaerobically Glucose (6C) Pyruvic Acid (3C) 2 ATP In PLANTS
2C ethanol + CO2 In ANIMALS
3C lactic Acid
Adenosine Triphosphate (ATP) :Adenosine Triphosphate (ATP) ATP is used in all cells to transfer chemical energy and so drive metabolic processes. It is used for:
muscle contraction
movement of cilia
movement of sperm tails
movement of the cell membrane during phagocytises
active transport
Movement of chromosome during meiosis... When ATP loses one of it’s phosphate groups (Pi) it becomes ADP
