Cell Organelles
This organelle is known as the "powerhouse" of the cell.
Mitochondria
Homeostasis refers to maintaining this type of internal environment.
Stable/Balanced internal environment
The movement of molecules from high to low concentration without energy.
Diffusion
Cells use this type of molecule to send messages to other cells.
Ligand
This is the jellylike substance that fills the inside of the cell.
Cytoplasm
This organelle controls all cell activities and contains DNA.
Nucleus
When body temperature rises, sweating helps cool the body. This is an example of which type of feedback?
Negative Feedback
Water moves across a membrane by this process.
Osmosis
The part of a cell that receives a signaling molecule is called a ____.
Receptor
The cell membrane is made mostly of this type of molecule.
Phospholipid
This organelle is responsible for packaging and shipping proteins.
Golgi Apparatus
The main control systems for homeostasis are located in this organ system.
Brain/Nervous System
Moving substances from low to high concentration requires this.
Active Transport
This type of signaling occurs when a cell sends a message to itself.
Autocrine Signaling
This type of transport uses vesicles to move substances into the cell.
Endocytosis
This organelle produces proteins and can be found floating in cytoplasm or attached to the rough ER.
Ribosomes
Child birth, migraines due to lack of water and platelets clotting your blood to help heal a wound are all examples of what?
Positive Feedback
These proteins help move large or charged molecules across the membrane.
Transport/Carrier Proteins
In cell signaling, the process of converting an external signal into a cellular response is called ____.
Transduction
This organelle helps maintain homeostasis by regulating what enters and leaves the cell.
Cell Membrane
This organelle breaks down waste materials and worn-out cell parts.
Lysosome
In homeostatic regulation, this component detects a change in the environment.
Receptor
When the concentration of solute is equal inside and outside the cell, the solution is said to be this.
Isotonic
This type of signaling involves hormones traveling through the bloodstream to distant target cells.
Endocrine Signaling
The process by which a cell responds to a signal and changes its behavior is called this.
Cellular Response/Cellular Communication
