A. Having allosteric enzyme set up?
Inhibitor binds to active site to speed up the reaction
B. Inhibitor binds to regulatory site to increase rate of reaction
C. Activator binds to regulatory site to activate the reaction.
D. Activator binds to active site to initiate the reaction
Which of the following is correct about the movement of water in plants?
A. moves against a water potential gradient
B. across the phloem tissue by diffusion
C. by using energy until it reaches to the xylem.
D. across the tissues of a plant by osmosis.
What will happen to the growth of the plant when you remove indole-acetic acid from the main shoot part of the plant?
A. The plant will bush out
B. It stimulates dropping of leaves.
C. The growth of side shoots will slow down.
D. The main shoot of the plant elongates
Answer (2)
The correct answers are: C for allosteric enzymes (activators enhance activity at regulatory sites), D for water movement in plants (water moves by osmosis), and A for IAA removal (plants tend to bush out). Together, these concepts highlight key aspects of plant biology and metabolism.
;
In summary, allosteric enzymes are regulated by activators that bind to regulatory sites, while water movement in plants occurs via osmosis. Removing indole-acetic acid from the main shoot typically encourages lateral growth or bushiness. Understanding these concepts is integral to plant biology. ;
