The answer is A, denature.
As each type of enzymes has its own optimum temperature, like the temperature that they work fastest at, so if the temperature goes too high above the optimum, the 3D structure of the enzyme breaks apart and deforms and they can no longer bind with substrates thus no longer works. In this scenario, we say the enzyme is denatured.
Note that only if the temperature is too high can make the enzyme denature, if the temperature is too low, instead, the enzyme would be inactive, but once the temperature goes back to normal, they work again. Unlike denatured enzymes, which does not work even if the temperature goes back to normal.
Answer:
water act as a reactant in light reaction.
Explanation:
Water undergo hydrolysis in presence of sunlight to form proton(H+) and hydroxyl ion(OH-) ion. The OH- ion liberates electron to reaction center of photosystem 1 thereby exciting the later .The excited photosystem then donates that extra electron to the primary electron acceptor and from the primary electron acceptor the electron moves through various electron carriers to generate ATP .
Basically water act as reducing agent in photosynthesis process.
Answer:
Use cooking methods that minimize/eliminate contact with water.
Explanation:
Vitamins are important nutrients found in fruits and vegetables. Vitamins can be easily leached out and it is therefore recommended that the vegetables should be consumed immediately after purchase or stored in an airtight container.
The use of cooking method that eliminate contact with water such as freezing, keeping in a close container will help retain the vitamins, reduce degradation rate and prevent it form been lost.
Cutting will allow easy definition of vitamins and result in its lost.
