Answer:
<h2>
merocrine, sebaceous, and apocrine</h2>
Explanation:
Merocrine: merocrine sweat glands are widely distributed across the body surface,
Sebaceous glands are located where hair follicles have existed,
apocrine sweat glands are found only in a few areas like axilla. Apocrine -are restricted to specific areas like the axilla, nipple of the breast, pubic region and around the anus area etc.
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.
The platelets begin to clump together to help stop the blood flow.
Without undergoing any changes itself, the enzyme makes changes to the substrate.
<h3>What is an enzyme?</h3>
An enzyme is a biological catalyst that acts by lowering the activation energy in a chemical reaction.
In a chemical reaction, an enzyme binds to a substrate to convert it to one or more products.
In conclusion, without undergoing any changes itself, the enzyme makes changes to the substrate.
