Distinguish passive-mediated transport, active transport, and secondary active transport.

Short Answer

Expert verified

In the passive mediated transport, the flow of ions across the cell membrane is without the requirement for energy input.

In the active mediated transport, the energy comes from the direct breakdown of ATP.

In the secondary active transport, the electrochemical gradient is formed by the pushing of ions out of the cells.

Step by step solution

01

Introduction

Transporters (membrane transport/carrier proteins) are membrane-spanning proteins that help carry ions, peptides, small molecules, lipids, and macromolecules across biological membranes.

02

Passive mediated transport

The flow of ions and other molecular substances across the cell membranewithout the requirement for energy input is referred to aspassive mediated transport. The transporter allows solutes, ions, and drugs to pass across the biological membrane.

03

Active transport

The energy is derived directly from the breakdown of ATPin the primary active transport. Because active transport is linked to the accumulation of large concentrations of substances that the cell requires, such as ions, glucose, and amino acids. Primary mediated transport is defined as a process that utilizes chemical energy.

04

Secondary active transport

Secondary active transport is a type of transport in which molecules are moved across the cell membrane without the need for ATP. The electrochemical gradientformed by pushing ions out of the cells provides this energy.
