Cell Organelles
in the mitochondria
Where does cellular respiration occur? or Where is energy created?
The fluid outside the cell.
What is extracellular fluid?
because it describes how the molecules are constantly changing position and is composed of many different kinds of molecule.
Why is it called the fluid mosaic model?
Active transport and Vesicular transport
Which types of transport require energy?
the non-cellular material that occupies space between the cells of connective tissue.
What is matrix?
The liquid part of the cytoplasm
What is cytosol?
To allow more diffusion into and out of the cell. To allow faster diffusion. To allow substance to move faster within the cell
it can allow certain molecules to pass through but restrict the passage of others
What does semi-permeable membrane mean?
refers to the use of proteins to cross the membrane.
What does 'facilitated' mean?
blood vessels, intestines and the stomach.
Name 3 organs where you'd find smooth muscle.
Flattened, membranous bags stacked on top of each other.
What is the structure of the Golgi body?
the cytoskeleton.
What gives a cell its shape?
a phosphate and a fatty acid.
What molecules make up a phospholipid?
protrudes out and engulfs the solid.
What does the cell membrane do in phagocytosis?
bone, adipose tissue, blood and cartilage.
What are examples of connective tissue?
The cytoskeleton, vesicles, cytoplasm and cell membrane.
Which parts of the cell are not organelles?
they can beat back and forth to move the entire cell or to move substances over the surface of the cell.
What are cilia and flagella?
acts as a physical barrier and regulates the passage of materials.
What are the 2 main functions of the cell membrane?
during carrier-mediated and active transport.
When are carrier proteins used?
skeletal muscle.
Which type of muscle do we have voluntary control over?
The production of lipids.
What is the function of the smooth ER?
because the concentration of solvent is higher outside the cell causing the solvent to move along the concentration gradient.
Why does a cell expand when you put it in a hypotonic solution?
only 2%.
without it, you can't create energy for active transport.
How does oxygen effect active transport?
no, they are close together.
Is there space between the cells of epithelium?
