The answer is C, hope this helps!
Answer:
Any process that involves active transport most often involves the expenditure of energy in the form of ATP hydrolysis.
Explanation:
Active transport in cells is a form of transport which involves the transport of solute molecules across a membrane against a concentration gradient using energy provided from some chemical reaction occuring in the cell.
Active transport is an endergonic (energy-requiring) process and therefore, must proceed only when coupled to an exergonic (energy-releasing) process such as the breakdown of ATP, an oxidation reaction, absorption of sunlight, etc.
In many instances in cell, such as the Na/K pump, ATP hydrolysis is the the common exergonic reaction to which active transport is coupled to.
Answer: B. They allow for specific substance to travel throughout the cell.
Explanation: I know this because carrier proteins and channel proteins are some types of embedded proteins.
The molecules that brings amino acids to the ribosomes are the tRNA molecules.
