Urease present in:
Correct answer: D. Soya bean
- A. Banana
- B. Grapes
- C. Soya sauce
- D. Soya bean
Explanation
Urease is an enzyme that catalyzes the hydrolysis of urea to produce ammonia and carbon dioxide. While urease is not specifically associated with soybeans, it is found in various organisms, including bacteria, fungi, and plants. Some plants, including soybeans, can contain urease. In soybeans and other legumes, urease plays a role in nitrogen metabolism. Legume plants often form symbiotic relationships with nitrogen-fixing bacteria known as rhizobia. Urease in the plant helps in the utilization of nitrogen compounds, and its activity can influence nitrogen availability in the soil.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
