Answer:
The shape of an enzyme determines which reaction it can catalyze.
Explanation:
Each enzyme is specific to one type of reaction. According to the structure of each enzyme, it has an active site capable of binding to a specific substrate, so the shape of the enzyme determines the type of reaction to be catalyzed.
Once the reaction occurs, the enzyme releases the product of the reaction and the enzyme is available for another reaction.
Regarding the other options:
- <em>The shape of an enzyme no depends on the reaction that it needs to catalyze.
</em>
- <em>Due to their specificity, enzymes can only catalyze one reaction at a time</em>
- <em>The shape of the enzyme is not altered after the reaction.</em>
It is absolutely False !! Abiotic factors are Co2 , light water !! Hope you get that !!
This cell city represents plant cell due to the presence of chloroplast.
<h3>What represents each part of the city?</h3>
In the cell city, the power plant represents mitochondria due to its production of energy. The storage tanks represent vacuoles because in cells in vacuoles materials are stored.
The transport company represents Golgi apparatus which also transport material within the cell, city hall represents nucleus because all the activities can be controlled from here.
The waste disposal plant represents Lysosomes because it removes waste. The construction site represents Ribosomes and Endoplasm Reticulum where proteins are produced. The food processing company represents Chloroplasts.
"Cell City" represent an plant cell because it has chloroplast which is only present in plant cell.

Answer:
None of the above.
Explanation:
GTPases are the regulatory proteins that are involved in the signal transduction pathway involving the activation of the G protein. The mutation in these proteins cal lead to cancer cells.
The guanine nucleotide exchange factors (GEF) allows the replacement of GDP by GTP. They activates the GTPase activity of the cell and can also activate the multiple GTPase activity of the cell. The Ras superfamily is activated by the GEF.
Thus, the correct answer is option (d).
Operational risk management is a continual cylic process that involves assessment of risk, risk decision making and execution of risk controls. it is a five step process and it is often used in planning. the five steps include identifying the hazard. hazard is anything with the potential of causing harm. the second step is assessment of hazard. this is followed by making risk decisions and fourth step execution of risk controls and finally supervision.
