1. The answer is "<span>the energy required to start the reaction".
</span>This energy is called as activation energy of the reaction. If the activation
energy is high, reaction is slow. Enzymes help to carry out the reaction by
a new path by reducing the activation energy. But the energy of reactants
and the products remain as same as without enzyme.
2. The answer is "reaction in cells would be too slow to sustain life<span>".
</span>If the activation energy is very high for the reaction, then that reaction will
be very slow and will require more time<span> to complete the reaction. Then survival is
very low. Hence, the roll of enzymes is very important to sustain life.</span>
<h3><u>Answer;</u></h3>
mechanoreception
In the context of sensation and perception, the detection of pressure by sensory receptors is called <u>mechanoreception</u>.
<h3><u>Explanation</u>;</h3>
- Mechanoreception involves detection and response towards certain kinds of stimuli such as touch, sound, and changes in pressure or posture.
- Mechanoreceptors are type of sensory receptors found on the skin and on other organs that detect sensations of touch. They are called mechanoreceptors because they are designed to detect mechanical sensations or differences in pressure.
Answer:
B is the answer I guess for the question
Macromolecules are mostly made up of monomers linked into polymers.
<h3>
What are macromolecules?</h3>
Macromolecules are made from subunits or building blocks of monomers. These monomers combine with one another through covalent bonds to form larger molecules that are called polymers.
Therefore, macromolecules are made of monomers which are subunits that make up polymer.

Answer:
Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.
Explanation:
Integrins are transmembrane protein receptors that attach the cell cytoskeleton to the extracellular matrix (ECM) in animal cells. These glycoproteins (integrins) are highly dynamic heterodimeric molecules that anchor cells in their position and transduce signals into and out of cells. Integrin-ligand binding activates signaling pathways that are involved in fundamental cellular functions including, among others, organization of the cell cytoskeleton, cell migration, regulation of the cell cycle, etc.
