Copper is absorbed by simple diffusion and _____ transport into intestinal cells.Multiple choice question.passiveactiveblood

Break Down the Problem

1. Identify the context of copper absorption in the body.
2. Understand the types of transport mechanisms in cellular physiology.

Relevant Concepts

1. Copper absorption is a physiological process often discussed in the context of how nutrients are taken up by intestinal cells.
2. The main types of transport mechanisms are passive transport (which does not require energy) and active transport (which requires energy to move substances against their concentration gradient).

Analysis and Detail

1. Passive Transport: Involves the movement of substances along their concentration gradient without the use of energy. Simple diffusion is a form of passive transport.
2. Active Transport: Involves moving substances against their concentration gradient, requiring energy, usually in the form of ATP.

Verify and Summarize

• Copper primarily enters intestinal cells via passive diffusion due to its ability to move along concentration gradients. However, it can also be facilitated by specific transport proteins that may require energy, indicating active transport as a secondary mechanism.

Final Answer

Copper is absorbed by simple diffusion and active transport into intestinal cells.
