Answer:
a. PPOs are denatured at high temperature
Explanation:
Polyphenol oxidase, PPO, is one of the most studied enzymes in the food industry as it is responsible for enzymatic browning reactions in fruits and vegetables. One of the reasons why its study is important is because commercially it is undesirable, since it modifies the sensory, nutritional and in general quality properties that impair the commercialization of a product.
The importance of controlling polyphenol oxidase is that it largely determines the quality and economic value of fruits and vegetables harvested, stored and processed. Bruising, chopping and other mechanical procedures damage the walls of fruits and vegetables which allows oxygen to penetrate, resulting in darkening or enzymatic browning reactions.
Enzymatic browning can be controlled through the use of chemical and physical methods, often used in combination. The commonly used physical methods are the reduction of temperature, oxygen and the use of modified atmospheres or coating films. The use of chemical methods will depend on what you want to inhibit, be it the enzyme, the substrate (oxygen or phenolic compounds) or the products.
Hello.
sometimes water just produces bubbles even without any plant in it! If the water is under pressure in the water pipes before you open the tap, then the water has lots of air dissolved in it and this will come out of solution when you leave it to stand. If you boil water, it will get rid of the air.
The gas bubbles generated during photosynthesis by aquatic plants produce distinctive sound pulses when leaving the plants. In photosynthesis of submerse water plants Oxygen emission occurs in form of bubbles which are released from the stomata or small openings caused by injuries.

True, the vitreous humor is a clear, watery fluid that helps maintain the intraocular pressure of the eye and provides nutrients for the avascular lens and cornea.
Vitreous humor is also known as aqueous humor or vitreous liquid. The word vitreous means transparent, and humor means liquid. It is a clear jelly-like substance that fills the inside of the eyeball. As a person ages, the vitreous humor becomes more liquid. It plays an important role in providing metabolic nutrient requirements of the lens, coordinating eye growth and providing support to the retina.
The cornea helps our eyes to focus light so we can see clearly. It is the transparent and front part of the human eye that covers the iris, anterior chamber, and pupil, along with the anterior chamber and lens.
