Cell Transport
Type of transport that uses energy, moves molecules against the concentration gradient
What is active transport
The process that allows the cell to transform reactants into the energy necessary for cellular functions
What is cellular respiration
The biomolecule that is the primary source of energy and is always found in a 1:2:1 ratio.
What are carbohydrates?
Doing this makes your blood glucose levels rise?
What is eating
Fruit ripening is this type of feedback loop.
What is positive
The type of transport that moves from an area of high concentration to an area of low concentration
What is passive transport?
products of cellular respiration
What are carbon dioxide, water, and ATP
This allows only certain substances to enter and exit the cell.
What is the cell membrane
The hormone that is released after eating food
What is insulin
Contractions during labor and childbirth are this type of feedback.
What is positive
Type of passive transport that moves water across a membrane from an area of high concentration to an area of low concentration.
What is osmosis?
reactants of cellular respiration
What are glucose and oxygen
the regulation of an organism's internal environment to keep the organism stable
What is homeostasis
The state of blood glucose level that causes glucagon to be released by the pancreas, which goes to the liver, prompting the release of glucose.
What is low blood sugar/glucose?
The type of feedback system that maintains homeostasis when conditions rise above, or drop below, set point
What is negative feedback?
This happens to the water in a cell in a hypertonic environment
What is lose water?
This is the energy required to move ions across a cell membrane
What is ATP
The reactants of photosynthesis.
What are water, carbon dioxide, and light energy?
The organ that produces insulin
What is the pancreas?
Role of stoma in maintaining homeostasis
What is regulating amount of water plant loses during transpiration?
Water flows across the cell membrane at the same rate in both directions in this type of solution
(hypotonic, hypertonic, or isotonic)
What is isotonic (equal amounts of solute/solvent inside and outside of the cell)
Why do you need to breathe more during heavy exercise?
Increased cellular respiration = increased oxygen input, increased carbon dioxide output
breathe in oxygen, breathe out carbon dioxide
The type of passive transport that uses a protein channel or carrier proteins to move molecules from an area of high concentration to an area of low concentration.
What is facilitated diffusion?
_______ cellular respiration requires oxygen and __________ cellular respiration does not require oxygen
What is aerobic and anaerobic?
Type of feedback loop that counteracts a stimulus to bring the body back to homeostasis.
What is negative?
