question 83

True/False

Channel proteins require energy for transporting molecules across the plasma membrane.

---

Definitions:

Nucleoli Disappear

A phenomenon occurring during the cell division process (specifically in prophase of mitosis) where the nucleolus breaks down and disappears.

Prophase

is the first stage of cell division in both mitosis and meiosis, characterized by the condensation of chromosomes and the breakdown of the nuclear envelope.

Receptor Protein

A molecule usually found on cell membranes that receives chemical signals from outside a cell, triggering an internal response.

Membrane Channel Protein

Membrane channel proteins are integral parts of cellular membranes, facilitating the selective transport of ions and molecules across the membrane.
