Cell Organelles
This organelle is the control center of the cell, housing DNA.
Nucleus
The plasma membrane is primarily composed of this type of molecule.
Phospholipid
This type of transport does not require energy and moves substances down their concentration gradient.
Passive Transport
This molecule is known as the cell’s “energy currency.”
ATP (adenosine triphosphate)
This process in the plasma membrane involves the cell engulfing large particles or cells by wrapping its membrane around them
phagocytosis
These small structures are responsible for protein synthesis
Ribosomes
These proteins are embedded in the plasma membrane and assist in the transport of molecules across the membrane
transport proteins
This type of passive transport uses protein channels to help molecules move across the membrane.
Facilitated diffusion
When ATP loses a phosphate group, it becomes this lower-energy molecule.
What is ADP (adenosine diphosphate)
This structure in the plasma membrane helps maintain fluidity by preventing phospholipids from packing too closely in low temperatures
cholesterol
This organelle is responsible for producing ATP, the cell's energy currency.
Mitochondria
This term describes molecules that have both hydrophilic and hydrophobic regions.
Amphipathic
Water moves across the plasma membrane by this process.
Osmosis
What type of reaction requires an input of energy to proceed, such as the synthesis of larger molecules from smaller ones?
endergonic reaction
These specialized cell junctions allow animal cells to communicate directly by transferring ions and small molecules between cells
gap junctions
This organelle contains enzymes to digest waste materials within the cell.
Lysosome
These carbohydrates attached to proteins on the plasma membrane help with cell recognition.
Glycoproteins
This form of active transport uses ATP to move ions against their concentration gradient.
Sodium-potassium pump or proton pump
This term describes what is required to start a chemical reaction
Activation energy
This type of cell junction in plant cells allows the exchange of water, ions, and small molecules between neighboring cells
plasmodesmata
This structure consists of a network of protein filaments that provides mechanical support to the cell, helps with intracellular transport, and enables cell movement.
cytoskeleton
This organelle is involved in the production of hydrogen peroxide and plays a role in lipid metabolism and detoxifying harmful substances.
Large molecules enter the cell through this active transport process involving vesicles.
Endocytosis
The balance between ATP production and consumption is maintained through this type of enzyme regulation
Feedback inhibition
Involves the cell taking in specific molecules bound to receptors on the cell surface
receptor-mediated endocytosis
