Biology Lecture Notes on Cellular Functions

These flashcards cover key concepts related to cell membrane structure and functions as noted in the lecture.

What does the term 'hydrophilic' refer to?

A substance that is attracted to water and can interact with it.

What are the functions of integral proteins in the cell membrane?

Transport, enzymatic activity, signaling, and cell recognition.

What is the definition of diffusion in biological terms?

The movement of molecules from an area of high concentration to an area of low concentration.

What type of membrane proteins are described as amphipathic?

Proteins that have both hydrophilic and hydrophobic regions.

What is meant by 'passive transport' in cellular processes?

The movement of molecules across a membrane without the use of energy, following the concentration gradient.
