Enzymes are biological catalysts. They speed up reactions although they are not changed in the reaction. Enzymes are proteins, and therefore are folded chains of amino acids with a specific shape. This shape is determined by the sequence of amino acids held together by bonds, for example Hydrogen bonds. Enzymes speed up reactions by bringing reactants together and reducing the activation energy required to start the reaction (enzymatic reaction).
Enzymes are specific: they have a specific shape, therefore only a certain substrate will fit its active site. There are two theories of enzyme action: Lock and Key and Induced Fit. The lock and key theory states that only a certain substrate will fit a certain active site, just like a key fits a lock. Induced Fit, likewise, states that enzymes wrap around substrates, attracted to each other by opposite charges, forming an enzyme substrate complex.
Options for the question have not been given. They are as follows:
A) parasitism
B) mutualism
C) inhibition
D) facilitation
E) commensalism
Answer:
D) facilitation
Explanation:
In ecology, facilitation is used to describe community interaction between two species in which at least one of the species is benefited. One species "facilitates" survival of another species and hence the term facilitation. They can provide facilitation by providing them refuge from predation, competition, physical stress etc.
Facilitation is broadly of two types, mutualism and commensalism. In mutualism, both the interacting organisms are benefited. In commensalism, one organism is benefited and another one is neither benefited nor harmed.
emotional comfort. according to some studies in psychological science, chicken soup is good for your emotions. the soup plays a great role in reducing the irritation that accompanies common cold. it emotionally and psychologically makes an individual to feel better. in fact individuals are encourage to over eat chicken noodle in the duration they suffer from the common cold.
The answer is A, diffusion
Answer:
xylem
Explanation:
xylem
The vascular system of plants has two transport tissues, called xylem and phloem. Xylem transports water and minerals, while phloem transports a variety of dissolved substances, including sugars and amino acids, throughout the plant.
