Answer: see explanation
Explanation:
A. substrate
B. Active site
C. Enzyme binds with substrate
D. Active site of enzyme
E. Products leaving active site
Simplified enzymatic reaction. The substrate reversibly binds to the active site of the enzyme, forming the enzyme-substrate (ES) complex. The bound substrate is converted to product by catalytic groups in the active site, forming the enzyme-product complex (EP). The bound products are released, returning the enzyme to its unbound form, ready to catalyze another round of converting substrate to product.

What is kingdom protista?
Organisms of kingdom Protista are simple eukaryotic organisms which are neither plants nor animals or fungi.These are unicellular organisms but can also exist in the form of colonies.
They live in water or damp terrestrial zones.Some of the organisms of kingdom Protista have cilia or flagella which helps the organism in locomotion.They are autotrophic or heterotrophic in nature.
Some protists may be more closely related to animals, plants, or fungi than they are to other protists. However, like the groups algae, invertebrates, and protozoans, the biological category protist is used for convenience. Others classify any unicellular eukaryotic microorganism as a protist.The study of protists is termed protistology.

Describe one way in which water from the ocean may make one complete cycle through the atmosphere and back to the ocean include the names in the cycle
Answer:
ocean water evaporates and becomes water vapor, then when the droplets grow larger they fall as precipitation
Explanation:
hope this helps mark me please
When ocean water evaporates and turns into water vapor, bigger droplets that have formed fall as precipitation and the cycle is named as water cycle.
What is water cycle?A cycle of events known as the "water cycle" includes precipitation in the form of rain and snow, drainage into streams and rivers, and return to the atmosphere through evaporation and transpiration. Water moves through this cycle between the earth's oceans, atmosphere, and land.
The water cycle demonstrates how water is constantly moving both inside the Earth and in the atmosphere.
It is a complicated system with a wide range of processes.
Liquid water evaporates to make water vapor, which subsequently condenses to form clouds and returns to earth as rain and snow.
The hydrologic cycle is crucial because it determines how water gets to people, plants, and other species.
Thus, when ocean water evaporates and turns into water vapor, bigger droplets that have formed fall as precipitation and the cycle is named as water cycle.

Which parts of Earth are most similar to the plate with an axis angle of 80°?
Answer:
The answer is below
Explanation:
The lines of latitude run from the east to the west and is used to measure the distance from the north to the south of the equator. There are different lines of latitude such as the equator (0°), north pole (90° N), south pole (90° S).
The North and South poles are most similar to the plate with an axis angle of 80° because sunlight hits these points at least at an axis angle of 80.
The size and shape of the earth is often based on its context and precision. The North and South poles are most similar to the plate with an axis angle of 80° this is because the sunlight often strikes these points at least at an axis angle of 80.
The radius of the Earth is commonly describe as the distance from Earth's center to its surface. It is known to be about 6,371 km.
There are different lines of latitude. There is the equator line which is 0°, north pole which is 90° N and south pole which is 90° S.

An anaphylactic reaction occurs because of a/an toxin-exotoxin interaction. sympathetic-parasympathetic interaction. antigen-antibody interaction. alpha-beta interaction.
Answer:
antigen-antibody interaction.
Explanation:
An anaphylactic reaction also known as anaphylaxis can be defined as a severe short-term allergic reaction that usually occurs within seconds or minutes after being exposed to an allergen.
Basically, an anaphylactic reaction is potentially life threatening i.e it is capable of causing death to patients and as such a medical diagnosis is required and it must be treated by a medical professional (expert) immediately after exposure to an allergen.
Hence, an anaphylactic reaction occurs because of an antigen-antibody interaction.
An epinephrine (adrenaline) may be quickly administered (given) to the patient by the medical professional.
Some of the symptoms of an anaphylactic reaction are;
I. Running nose and sneezing.
II. Skin rash.
III. Dizziness, fainting, vomiting, paleness, diarrhea etc.
