21 окт. 2015 г. · Transports like diffusion, facilitated diffusion and osmosis do not require energy. Active transports like phagocytosis, exocytosis, require energy.

Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.

Active transport requires cellular energy to achieve this movement. There are two types of active transport: primary active transport that uses adenosine ...

12 сент. 2022 г. · Active transport requires energy for the process by transporting molecules against a concentration or electrochemical gradient.

This transport can occur through passive mechanisms like diffusion and osmosis or active processes such as active transport, which require energy input, ...

Passive transport: This does not require any energy expenditure as it occurs along the concentration gradient of the molecule being translocated.

Active transport is a process that is required to move molecules against a concentration gradient. The process requires energy.

9 янв. 2020 г. · ... molecular transportation require energy ... transport is the movement of molecules against the concentration gradient and requires energy.

5 нояб. 2016 г. · If by passive transfer you mean simple diffusive, down-gradient transport, aka molecular diffusion, energy is needed to maintain the gradient ...
