Definitions
This mechanism stops a change in order to maintain homeostasis.
Negative feedback
This molecule has a hydrophilic head and hydrophobic tails.
Phospholipid
This type of transport requires no energy.
Passive Transport
This is the diffusion of water across a membrane.
Osmosis
This reaction uses sunlight to create ATP and NADPH.
Light Dependent Reactions
This term describes something that is “water fearing.”
Hydrophobic
This structure allows certain molecules to pass through the membrane during facilitated diffusion.
Channel Proteins
This type of transport requires ATP.
Active Transport
This type of solution has a high concentration of solutes.
Hypertonic
This reaction uses carbon dioxide to make glucose.
Light Independent Reactions (Calvin Cycle)
This term describes something that is “water loving.”
Hydrophilic
Small, ______ molecules pass directly through the phospholipid bilayer.
Nonpolar
This process moves materials into the cell using vesicles.
Endocytosis
This type of solution has a low concentration of solutes.
Hypotonic
This is the overall equation for photosynthesis.
6 CO₂ + 6 H₂O → 6 O₂ + C₆H₁₂O₆?
This structure makes up most of the cell membrane and has two layers.
Phospholipid bilayer
Large or polar molecules must use this type of structure to cross the membrane.
A protein (channel or pump)
This process moves materials out of the cell using vesicles.
Exocytosis
This type of solution has equal solute concentration compared to another solution.
Isotonic
This is the main purpose of the light dependent reactions.
To make ATP and NADPH
This describes a membrane that controls what moves in and out based on size and charge.
What is selectively permeable?
This property of the membrane explains why some substances can pass through while others cannot.
Selective Permeability
This specific active transport protein moves sodium and potassium across the membrane.
The Sodium-Potassium Pump
In osmosis, water moves from this type of solution to this type of solution.
Water moves from high to low concentration.
Hypotonic (low solute, high water) to Hypertonic (high solute, low water).
This is the main purpose of the Calvin Cycle.
