A. pores and channels B. enzymes C. receptors D. all of these are functions - All of these are functions (Remember: "Peripheral proteins" are on the surface of the plasma membrane of the cell) The organelle that functions to synthesize membrane integral proteins and phospholipids are the ______. A. rough endoplasmic reticulum B. plasma membrane C. smooth endoplasmic reticulum D. cytosol - Rough Endoplasmic Reticulum (Rough ER) ATP via aerobic cellular respiration is produced by the golgi apparatus.

Centrioles function as enzyme-containing sacs that digest worn out cell parts or unwanted substances, bacteria, viruses, and toxins. True or False? - False (That would be Lysosomes!) The cilia are short hair-like projections that propel substances on cell surface. True or False? - True Which of the following is an "active" physiological process? A. filtration B. diffusion C. osmosis D. endocytosis - Endocytosis (Remember: anything with Diffusion, Osmosis, or Filtration is PASSIVE!) Page 3/8 ©EmilyCharlene 2024. All Rights Reserved. Which solution tonicity would cause crenation of a red blood cell? A. hypertonic B. isotonic C. hypotonic D. gin and tonic - Hypertonic Remember: Crenation means "shrink"! Cells shrink in a hypertonic solution when water moves from inside the cell to the outside because the solution has a higher osmolarity (high solute concentration, low water concentration) than inside the cell! When solute concentration goes up, water concentration goes down! Water moves by Osmosis from areas of low solute (high water) to high areas of solute (low water)! The sodium potassium pump pumps _____ out and _____ into the cell. A. 2 sodium; 3 potassium B. 3 potassium; 2 sodium C. 3 sodium; 2 potassium D. 2 potasium; 3 sodium - 3 Sodium Out; 2 Potassium Into
