What are the options given?
Answer:
B) Feedback inhibition
Explanation:
Feedback inhibition is a situation in which the end product of a reaction controls the action of the enzyme that helped produce it. In this process the end products formed at the end of a sequence of reactions participate in inhibiting the activity of the enzymes that helped synthesis the end product. Some examples of products that are used in feedback inhibition are CTP, citrate and Isoleucine. While negative feedback is used in the context of inhibition, negative feedback may also be used for promoting a certain process.
Therefore, when the end product of a pathway inhibits catalysis of the first step of that pathway, this phenomenon is called Feedback inhibition.
Yes Carbon dioxide is necessary for photosynthesis because Photosynthesis didn't go on because there was no Carbon dioxide in flask X.
The carbon dioxide was absorbed by the sodium hydroxide. In flask Y, the colour of the iodine solution turned blue black. This is because starch was present in the leaf of flask Y. Starch was present because it underwent photosynthesis.
I think the most critical consequence of the advancement of the amniotic egg it the tetrapods were no longer attached to the water for reproduction.The amniotic egg permits reptiles, flying creatures, and warm-blooded creatures to lay eggs ashore without drying out. The liquid filled depression containing the incipient organism is isolated from the outer condition by an amniotic sac that is impermeable to water.
