Answer:
The correct answer is "receptors".
Explanation:
Virus infect and reproduce by recognizing specific receptors in their host cells. Virus-receptor binding is highly specific, this is the reason why some virus can infect only certain animals or plants at specific tissues. If the virus that causes avian flu attaches only to the cells of the lower part of the respiratory system, it is very likely that these cells have specific receptors that are not present in the upper part of the respiratory system, receptors that the viruses recognize.
Fungi= basidiomycota
animalia= insect
plantae= cactus
I believe its called sublimation
Secondary active transport protein link the transport of an ion downward its gradient with the transport of another particle against its gradient, whereas primary active carrier proteins move both components in the opposite direction of their respective gradients.
<h3>Which proteins are essential for active transport?</h3>
Instead of channel proteins, carrier proteins are used in active transport. Since these carrier proteins require ATP to change shape, they differ from those seen in facilitated diffusion.
<h3>Why do proteins play a part in active transport?</h3>
- Specialized carrier proteins are needed for active transport, and cellular energy must be used.
- When a chemical's phospholipid bilayer is impermeable to it or when there is a concentration gradient, carrier proteins allow chemicals to pass through the membrane.
<h3>What kinds of proteins are carriers?</h3>
The carrier proteins can be categorized as being driven by ATP, electrochemical potential, or light, depending on the source of energy.
