Transport across the cell membrane & intracellular transport

What are vesicles?

small, fluid-filled sacs with a membrane

which process for beta cells of the pancreas use to simultaneously EXPORT multiple copies of insulin stored in vesicles?

excytosis

which process enables cancer cells to EXPORT multiple copies of growth factors stored in vesicles to stimulate new blood vessel formation?

Excotytosis

Why do your cells require endocytosis?

essential functions like taking in nutrients, eliminating pathogens.

What are some functions of pinocytosis?

absorb dissolved substances from extracellular fluid and maintain cellular homeostatsis

What is the function of receptor mediated endocytosis?

effciently and selectively transports specific molecules by using receptor proteins

What enables your macrophages to import bacteria & viruses for destruction?

phagocytosis

Which three types of protein filaments form the cytoskeleton?

Microfilaments, intermediate filaments, and microtubles

Which motor proteins use the energy of ATP to move along acting filaments?

myosine

Which motor proteins use the energy of ATP to move along microtobles?

dynein

Which proteins enable motor proteins to attach to the substances they transport?

adaptor proteins or linker proteins

Small hydrophillic subtance must cross the cell membrane from lower concentration to higher concentration. Which process performs this type of transport?

Active transport

active transport proteins move small hydrophillic ions and small hydrophillic molecules from lower concentration to higher concentration. Which energy source drives active transport?

ATP

Some active transport proteins enable cancer cells to export anto-cancer drugs and attain drug resistance. These membrane transport proteins are.

Multi-drug resistance proteins (MDR)

Which process enables your cell membrane to import large substances that cant be transported by carrier or channel proteins?

Endocytosis

Which process enables you white blood cells to import SARS CoV-2 to destroy it

Phagocytosis

Which process enables your cells to sample the substance in the extracellular fluid that surrounds your cells?

Pinocytosis

Endocytosis

A process where a cell takes in substances from outside by engulfing them with its cell membrane creating a vehicle that moves into the cell

Phagocytosis

process where a cell engulfs and digest large particles like microorganism or debris using its plasma membrane to form a phagosome

phagosome

membrane bound vesicle that forms in a phagocyte to engulf a particle during the process of phagocytosis

macrophage

A type of white blood cells that engulfs and kills microorganism, removes dead cells, and activates other immune cells to fight infection and maintain tissue health.

Pinocytosis

process by which a cell takes in fluids and dissolved substances from its enviroment

What enables your cells to recognize a specific molecule or particle and import it?

Receptor-mediated endocytosis

Which process enables your cell membrane to export large molecules & large particles

Exocytosis

Which process enables your beta cells to export many copies of the insulin hormone molecule simultaneously?

Exocytosis

Which energy source enables the motor proteins to transport substances by moving along the microtubule surface?

ATP

Endocytosis

IMPORT entire cells, large particles, substances dissolved in extracellular fluid, and viruses

Exocytosis

EXPORT multiple copies of large hydrophilic molecules form the cell to the extracellular fluid

Phagocytosis

“Cell eating”

myosine

motor proteins that interact with acting filaments in cytoskeleton

dynein

microtubule motor proteins that moves cargo towards the minus ends of microtubules
