Definition

1. Noun:
   • A complex of enzymes that cause glycolysis; originally found in yeast but also present in higher organisms: "Zymase" refers to a specific mixture or complex of enzymes responsible for catalyzing the chemical reactions of glycolysis, the metabolic pathway that converts glucose into pyruvate. It was first identified in yeast cells but is also present in the cells of more complex organisms.

Usage Examples

• Noun:
  • The discovery of zymase was crucial for understanding fermentation.
  • Zymase activity is essential for the energy production in yeast during bread making.

Advanced Usage

• Scientific Context: In biochemistry, "zymase" is a historical term often used to describe the fermentative enzyme complex isolated from yeast. In modern terminology, the individual enzymes (e.g., hexokinase, phosphofructokinase) are often discussed separately, but "zymase" can still refer to the collective system.
  • Early 20th-century research focused on isolating and characterizing the components of zymase.

Variants and Related Words

• Zymology (n): The scientific study of fermentation.
• Enzyme (n): A protein that acts as a catalyst to speed up a specific biochemical reaction.
• Glycolysis (n): The metabolic pathway that breaks down glucose into pyruvate.

Synonyms

• Ferment (n, in a specific historical/technical context): An agent, such as yeast, that causes fermentation.
• Enzyme complex (n): A group of enzymes that work together in a sequence.

Notes on Meaning

• The term "zymase" is primarily used in historical, biochemical, and microbiological contexts. It is not a common word in everyday English but is important in scientific discussions about metabolism and fermentation. Its meaning is highly specific and refers to the functional collection of enzymes for glycolysis.
