To answer this we need to analyze each statement
camouflage, mimicry, and stingers: This is meant to escape predation and fend off predators, so this is the correct answer.
hibernation and migration: This is meant for breeding and or food energy storage, to pass hard seasons so is also incorrect.
courtship and breeding behaviors: This is meant for reproduction and to ensure offspring so this is incorrect.
nesting and food gathering: this is a behavior for survival, resource use rather than defense, si this is not correct.
Answer :B. By changing the shape of the enzyme's active site.
check the attachment
Explanation: This is a type of inhibition , in which a molecule binds to another part of the enzyme instead of the active site.
On binding, it disrupts the normal hydrogen bond and hydrophobic interactions holding the enzyme molecule in its three dimensional shape, therefore distorting the conformation and ACTIVE SITE of the enzyme (changed it shape).
Since the active site is the precise location enzyme must bind with substrates for enzymatic reactions,this makes the enzyme not fit for binding with the substrate, therefore the efficiency is reduced. No substrate-enzyme complex, and hence no substrate-product complex for the release of products, this brings down the turnover rate and eventually
<u>the rate of reaction of the enzyme</u>
Thus, the enzyme function is totally blocked, even in high concentration of the substrate,
Answer:
C)Both proteins bind ATP and F-actin
*C option is not mentioned* there is a flaw in the question
Explanation:
Two families of motor proteins, kinesin and dynein, transport membrane-bounded vesicles, proteins, and organelles along microtubules. Nearly all kinesins move cargo toward the (+) end of microtubules (anterograde transport), whereas dyneins transport cargo toward the (−) end (retrograde transport).While
both the protiens have globular ATP-binding heads that function as the motor domain and interact with the microtubules.
Produced during ATP synthase in the mitochondria
