Anaerobic metabolism activation
noun phrasePronunciation: /ˌænæˈroʊbɪk metəˈbɒlɪzəm ˌæktɪˈveɪʃən/
The metabolic shift toward oxygen-independent biochemical pathways such as fermentation and ethanol production when plant roots are exposed to hypoxic or anoxic conditions during flooding or waterlogging. This prevents complete metabolic collapse in low-oxygen environments.
Plain English
The switch to energy production without oxygen when plant roots are submerged or deprived of air.
Etymology & History
Usage
"Rapid anaerobic metabolism activation allows flood-tolerant rice varieties to survive extended waterlogging events."
Style guide notes: Specify 'anaerobic fermentation' if clarifying the pathway; standalone 'anaerobic metabolism' may include multiple mechanisms.

Frequently Asked Questions
What are the main products of anaerobic metabolism in plants?
Ethanol, lactate, and alanine are primary end products; plants use different pathways by species.
How does anaerobic metabolism affect plant survival during floods?
It maintains minimal ATP production, extending survival until aerobic conditions return or plant dies.
Why Test Candidates on This?
Important for understanding crop performance in regions with frequent flooding and breeding flood-resilient varieties.
