Transport 1
Passive transport moves substances from _______ concentration to ______ concentration.
high to low
Active transport moves substances from _______ concentration to ______ concentration.
low to high
What is ONE reactant (input) of Photosynthesis?
Water, CO2, Sunlight
What is ONE reactant (input) of Cellular Respiration?
Oxygen, Glucose
What type of transport moves molecules AGAINST the concentration gradient?
Active transport
Passive transport continues until ....
equilibrium is reached
What is the main difference between passive and active transport?
Active transport requires energy while passive transport does not.
In what types of cells does Photosynthesis take place?
Plant, algae, and some bacteria cells.
In what organelle does Cellular Respiration take place?
Mitochondria
The cell membrane is described as being selectively permeable. What does this mean?
It allows certain substances to pass through more easily.
What is the diffusion of water across a semi-permeable membrane called?
Osmosis
Which type(s) of transport moves large molecules?
active transport and facilitated diffusion
What is ONE product (output) of Photosynthesis?
glucose, oxygen
What is ONE product (output) of Cellular Respiration?
ATP energy, CO2, water
Which step of Cellular Respiration takes place in the cytoplasm of the cell?
Glycolysis
Which type(s) of transport moves ions like sodium and potassium?
Active transport and facilitated diffusion
Which type of passive transport moves molecules directly across the cell membrane?
Diffusion
In what organelle does Photosynthesis take place?
Chloroplast
How much ATP is produced at the end of Cellular Respiration?
38
Write a sentence that compares the reactants and products of photosynthesis with the reactants and products of cellular respiration.
The reactants of one process (photosynthesis or cellular respiration) are the products of the other process.
What is needed for facilitated diffusion to work? Why?
A membrane spanning protein is needed for facilitated diffusion to work because without it the substance being transported would not be able to enter/exit the cell.
What are the TWO ways in which active transport takes place?
Through transport proteins and transport vesicles.
What are the TWO types of reactions taking place during Photosynthesis?
Light-Independent and Light-Dependent reactions
What are the THREE steps of Cellular Respiration, in order?
Glycolysis, Krebs Cycle, Electron Transport Chain
What would happen to our general food supply if the sun's energy was no longer available?
We would lose out food supply since at some point the vast majority (chemosynthetic organisms excluded) of living organisms get their energy from the sun. The sun's energy moves it's way up the food chain, so without the sun's energy there would be no food.
