Chapter 2 Flashcards
All of the functions of the cell (plasma) membrane
- Separates intracellular fluid from extracellular fluid
- Regulates entry and exit of ions, nutrients, and waste
- Creates an electrical charge difference
- Attaches receptors for self-recognition and communication
Ciliary movement
Fast forward strokes to move fluid
Flagellated movement
Propels a sperm forward
Ameboid movement
Migration of embryonic cells, macrophages, and fibroblasts
Muscle contractions
Actin and Myosin interactions
Proteins in RNA
Ribose, Uracil, Cytosine, Guanine, Adenine
What makes up the LARGEST percentage of a typical cell membrane?
Proteins
Which cellular mechanism occurs to move mucus through the respiratory tract?
Ciliary movement
Cholesterol and triglycerides contribute to the ________ portion of protoplasm
Lipid
What are purines
Adenine, Guanine
What are pyrimidines
Thymine, Cytosine, Uracil
Chemotaxis is the stimulus that drives the ________ of macrophages, fibroblasts, and embryonic cells
ameboid movement
