Answer:
Explanation:
When enzyme does not work properly it is said to be inactive and this affect its efficiency.
Substrate concentration - Enzyme requires adequate substrate concentration to be effective, when the concentration is high the enzyme activity increases and when it is low it decreases.
Temperature - Enzymes are more active at specific temperature at very high temperature enzyme can be denatured leading to a loss of its activity. Hence, enzyme should be made to work at its optimum.
pH- Enzymes are active at specific pH, when the pH is altered enzymatic activity may be reduced or enzyme become inactive. Hence, pH of enzymes should be maitained.
Answer:
<h2>G protein-linked receptor, GTP, and effector protein</h2>
Explanation:
G protein coupled receptor is a seven trans-membrane protein, when ligand binds to the receptor ,it activate the receptor which in turn activate the G protein. In inactive form, G protein binds to GDP, but when it become active ,GDP is replaced by GTP. After activation the beta and gama sub-unit separates from the alpha sub-unit . Alpha sub-unit with bind GTP finally activates the effector protein, which then moves into the nucleus and activate or repress the transcription.
B. You can survive and get materials then find a way back
The nitrogen in the air cannot be used by producers and consumers. It must be fixed or converted by bacteria in the ground into a useable form for plants called nitrates. Some plants called legumes (beans and clover) actually have bacteria in their roots.
