Chapter 3 Flashcards
What are functions of the smooth ER?
It has various functions including lipid synthesis in some cells and distribution by vesicle formation
What are functions of a cell wall
Support and protection
What are functions of the centriole?
Formation of basal bodies
What are functions of the rough ER?
Synthesis, and/or modification of proteins and other substances
The molecule —– is used to fuel all energy dependent cellular processes.
ATP
What are 3 components of the cytoplasm?
Water
Dissolved organic molecules
Salts
The action known as —– involves the release of materials from the cell via vesicles that fuse with the plasma membrane.
Secretion
The vesicles that function in the metabolism of fatty acids in a cell are called ——-.
Peroxisomes
—– are vesicles that contain enzymes for digesting all macromolecules
Lysosomes
Centrioles are formed from ———.
Microtubules
—- and —- are the molecules that control cell contraction (muscles).
Actin, myosin
What roles do microtubules play in eukaryotic cells?
Cilia and flagella
Cell shape
Organelle movement
All cells, except prokaryotes, complete cellular respiration in the ——–.
Mitochondria
Liver and kidney cells filter and destroy many toxins. As a result they contain high numbers of the organelle ——-.
Peroxisomes
What are functions of the cytoskeleton?
Cellular structural support
Aids in cell division
Intracellular transport
What are functions of the intermediate filaments?
Support of the nuclear envelope and the plasma membrane
Formation of cell-to-cell junctions
—– are long thin appendages used for locomotion.
Flagella
—— are short appendages used for attachment
Fimbriae
—— are gelatinous sheath which surrounds and protects the cell
Capsule
The —— is an organelle that is assembled in the nucleolus of the nucleus.
Ribosome
What does the cell theory state?
That all cells come from pre-existing cells
That all organisms are made up of cells
When ribosomes in a cells cytoplasm are attached to an organelle, that organelle now studded with ribosomes is then called rough ———- ——–.
Endoplasmic reticulum
Molecules that can attach, detach, and reattach to an actin filament to produce movement are called —– ——.
Motor molecules
The genetic material of a eukaryotic cell is located in the ——–, while in a prokaryotic it is located in the ——– region.
Nucleus
Nucloid
