Verified step by step guidance

Understand the role of ATP in cellular transport: ATP (adenosine triphosphate) is the primary energy currency of the cell, providing energy for various cellular processes, including active transport.

Differentiate between active and passive transport: Active transport requires energy, often in the form of ATP, to move substances against their concentration gradient. Passive transport, such as diffusion, does not require energy and occurs along the concentration gradient.

Consider the impact of ATP loss: Without ATP, the cell cannot perform active transport because there is no energy available to move substances against their concentration gradient.

Evaluate passive transport capabilities: Even without ATP, passive transport can still occur because it does not require energy. Substances can still move across the cell membrane through diffusion or facilitated diffusion.

Conclude the effect on transport: With the loss of ATP production, the cell would only be able to transport substances using passive diffusion, as active transport processes would cease due to the lack of energy.
