Cell Transport
This type of transport does not require energy and moves molecules from high to low concentration.
What is passive transport?
Osmosis is the movement of this molecule across a semipermeable membrane.
What is water?
This term describes a state in which the body keeps conditions relatively stable so it can function properly.
What is homeostasis?
The cell membrane is primarily made of this type of bilayer.
What are phospholipids?
The building blocks of proteins are these.
What are amino acids?
This part of the membrane allows charged ions to move across the membrane without energy.
What is an ion channel (or channel protein)?
A solution with equal solute concentration compared to the cell is called this.
What is isotonic?
Each body condition has this “ideal level” it tries to maintain.
What is a set point?
This term describes the flexible, moving nature of the membrane structure.
What is the fluid mosaic model?
DNA and RNA belong to this class of macromolecules.
What are nucleic acids?
The movement of large molecules into the cell using vesicles is this type of transport. (Active or passive?)
What is active?
In a hypertonic solution, water will move in this direction relative to the cell.
What is out of the cell?
The four parts of a feedback loop are stimulus, sensor, control center, and this.
What is the effector?
Proteins that span the membrane are called this type of protein.
What are channel/carrier proteins?
Fats, oils, and waxes are examples of this type of macromolecule.
What are lipids?
This form of active transport moves sodium out of the cell and potassium in, using ATP.
What is the sodium-potassium protein pump
Plant cells become turgid (full) when placed in this type of solution.
What is a hypotonic solution?
When body temperature rises, this structure in the brain compares it to the set point and signals responses like sweating.
What is the hypothalamus?
This molecule is attached to proteins or lipids in the membrane to serve as ID tags.
What are carbohydrates?
The bond formed between two amino acids is called this.
What is a peptide bond?
Bulk transport can be broken into two types: one for “in” and one for “exit.” Name both.
Endocytosis & Exocytosis
When animal cells burst due to excessive water intake, the process is called this.
What is cytolysis (or lysis)?
Feedback can either reduce a change to return to set point or increase a change. Name both types.
What are negative feedback and positive feedback?
This property of the membrane allows certain substances in and out but not others.
What is selective permeability (or semipermeability)?
The elements make up nucleic acids.
