What is alcohol fermentation?
An anaerobic process used by yeast cells to regenerate NAD⁺ so glycolysis can continue
Where does alcohol fermentation occur?
In yeast cells under anaerobic (low or no oxygen) conditions.
What is the first step before alcohol fermentation?
Glycolysis.
What is the overall reaction of glycolysis?
Glucose → 2 Pyruvate.
How many ATP are produced during glycolysis?
2 ATP (net)
How many NADH are produced during glycolysis?
2 NADH.
What happens to pyruvate during alcohol fermentation?
2 Pyruvate → 2 Ethanol + 2 CO₂.
What are the products of alcohol fermentation?
Ethanol and carbon dioxide (CO₂).
How many CO₂ molecules are produced from 2 pyruvate?
2 CO₂.
What happens to NADH during alcohol fermentation?
2 NADH are oxidized to 2 NAD⁺.
Why is NAD⁺ regenerated during alcohol fermentation?
So glycolysis can continue producing ATP.
Does alcohol fermentation produce ATP directly?
No, ATP is produced during glycolysis.
What is the net ATP gain from alcohol fermentation and glycolysis together?
2 ATP per glucose molecule
hat is the purpose of alcohol fermentation?
To regenerate NAD⁺ and allow glycolysis to continue in the absence of oxygen.
What is the overall pathway of alcohol fermentation?
Glucose → 2 Pyruvate → 2 Ethanol + 2 CO₂.
What is lactic acid fermentation?
An anaerobic process that regenerates NAD⁺ so glycolysis can continue.
Where does lactic acid fermentation occur?
In human muscle cells when oxygen is limited.
hat is the first step before lactic acid fermentation?
Glycolysis.
What is the overall reaction of glycolysis?
Glucose → 2 Pyruvate
How many ATP are produced during glycolysis?
2 ATP (net)
How many NADH are produced during glycolysis?
2 NADH
What happens to pyruvate during lactic acid fermentation?
2 Pyruvate → 2 Lactate.
What is the end product of lactic acid fermentation?
Lactate (lactic acid)
What happens to NADH during lactic acid fermentation?
2 NADH are oxidized to 2 NAD⁺.
Why is NAD⁺ regenerated during lactic acid fermentation?
So glycolysis can continue producing ATP.
Does lactic acid fermentation produce ATP directly?
no, ATP is produced during glycolysis not lactic acid fermentation
What is the net ATP gain from lactic acid fermentation and glycolysis together?
2 ATP per glucose molecule.
What is the purpose of lactic acid fermentation?
To regenerate NAD⁺ and allow glycolysis to continue when oxygen is unavailable.
What are the products of glycolysis that enter lactic acid fermentation?
2 Pyruvate and 2 NADH
What is the overall pathway of lactic acid fermentation?
Glucose → 2 Pyruvate → 2 Lactate.
What type of respiration is lactic acid fermentation associated with?
Anaerobic respiration
What happens to pyruvate in the absence of oxygen?
It is converted into lactate.
Why do muscle cells use lactic acid fermentation?
To keep producing ATP when oxygen supply cannot meet demand.
