Answer:
An enzyme-substrate complex is a temporary molecule formed when an enzyme comes into perfect contact with its substrate.
Explanation:
Answer:
In an organ, different tissues work together to carry out a particular function. These are the main organs, as well as their primary function:
The brain controls thoughts, memory and other organs.
The heart pumps blood around the body.
The lungs separate oxygen from the air and remove carbon dioxide from the blood.
The stomach helps to digest food.
The intestines absorb nutrients from food.
The liver removes poisons from the blood.
The kidneys filter blood and produce urine.
The bladder stores urine.
The skin protects and contains the other organs.
Answer:
it's particles vibrate in place
Explanation:
They have a fixed volume and shape
No, the diffusion distance does not differ between the cubes.
<u>Explanation:</u>
Diffusion is the process by which materials get transported from higher concentration to lower concentration. How much ever the cube size is the rate of diffusion remains the same. Depending on the size the diffusion will not happen at once. The more the volume and lesser the surface area diffusion take a longer time.
To transport the materials through the cells through diffusion takes longer time and hence higher organisms have specified organs to help them in this diffusion.
Answer:
C. The inhibitor binds to the enzyme's active site, because its shape is similar to that of the substrate.
Explanation:
An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy. Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.
Generally, enzymes function best at a specific pH and temperature level. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.
An allosteric effector can be defined as an agent, organ or molecule that is being binded to an enzyme at a site, thereby causing a reduction (negative effect) or an increase (positive effect) in an enzyme activity.
An inhibitor is any substance that slows down or stops a biological process or chemical reaction.
Hence, the statement which best describes the function of a competitive inhibitor in an enzyme-catalyzed reaction is that the inhibitor binds to the enzyme's active site, because its shape is similar to that of the substrate and consequently, slowing down or stopping the process.
