Cell transport
Cell transport that requires ATP energy is called...
Active transport
The organelle that performs cellular respiration in ALL plant and animal cells.
mitochondria?
What is the chemical formula for carbon dioxide?
CO2
The organelle in which photosynthesis occurs.
What are Chloroplasts?
What is the form of usable energy for all living cells?
ATP energy
What happens during cell transport
Molecules move in and out of cells across the cell membrane
The main purpose of respiration is to release this from glucose
Energy in the form of ATP
What is the formula for glucose?
C6H12O6
What are the reactants of photosynthesis?
Carbon Dioxide, Water
What is the main source of energy for almost all life on Earth?
Sunlight
Name one of the 3 types of passive transport (does not require ATP energy)
Diffusion
Osmosis
Facilitated diffusion
What are the reactants of cellular respiration?
Glucose and Oxygen
What is the name for the ingredients in a chemical reaction?
What is the name for the molecules you make in a chemical reaction?
Reactants (ingredients)
Products (what you make)
What are the products of Photosynthesis?
Glucose and Oxygen.
Who performs photosynthesis?
Who performs cellular respiration?
Photosynthesis: Plants (+ algae and cyanobacteria)
Cellular respiration: All living things (all living things need ATP energy)
When water molecules move from high to low concentration it is called...
Osmosis
What are the products of cellular respiration?
Carbon Dioxide, Water (and ATP)
Describe the relationship between the photosynthesis equation and the equation for cellular respiration
The products of one reaction are the reactants of the other.
(They are opposites and materials cycle between them)
Where does the energy that is stored in glucose during photosynthesis come from?
Sunlight
What molecule that is made during photosynthesis is broken down for ATP energy during cellular respiration?
Glucose (sugar)
Describe the structure of a cell membrane
***Must identify two characteristics of cell membrane structure
The cell membrane...
- has two layers (bilayer)
- is made of phospholipids (a type of lipid)
- is described as a fluid mosaic because its flexible
- has proteins embedded in it
- has cholesterol to space out the lipid molecules
- is surrounded by water on either side
Do plant cells have mitochondria for cellular respiration? Why or why not?
YES, all living things perform cellular respiration
Plants need to break down the glucose made in photosynthesis in order to get ATP energy!
Sunlight --> Glucose --> ATP energy
What molecule do the carbon atoms plants use to make glucose come from?
They come from CO2 (carbon dioxide)
6CO2 + 6H2O --> C6H12O6 + 6O2
How many atoms of oxygen are used in the reactants for photosynthesis?
Reactants:
6CO2 + 6H2O
18
6CO2 + 6H2O
12 + 6
What type of macromolecule is glucose used as a building block for?
Carbohydrates
