What is the equation for cellular Respiration? 6CO2 + C6H12O6 --> 6CO2 + 6H2O + Energy
Why is it essential for some organisms to use both fermentation and anaerobic respiration? It allows for increased ATP production when Oxygen is limited
Movements of energy and nutrients through living systems are different because... Energy flows in 1 direction and nutrients recycle
What would happen if you removed carbon dioxide from a plant's environment? Fewer sugars would be produced
What is the Golgi Apparatus job? To manage the process by which proteins are sorted and packaged to be sent where they are needed
What are the channels, within the cell membrane, that help move materials from 1 side to the other made of? protein
A cell membrane is selectively permeable to water, if a Red blood cell was placed into highly concentrated salt water, what would happen? Water would leave the cell, decreasing in size
What is active transport? The transportation of molecules into and out of the sell using energy.
The net movement of molecules from a high concentration to a low concentration is called... Diffusion
The movement of water across a selectively permeable membrane os called... Osmosis
An animal cell surrounded by pure water will burst because osmosis would cause.... water to move into the cell
Carbon Dioxide, Water and Glucose are ALL products of... photosynthesis
When a phosphate group is removed energy is released from ATP
After amino acids are strung together by ribosomes, the amino acid chain is able to enter what organelle? Rough ER
What is the Nucleus job? Store DNA, Contain information to make proteins, holds ribosome synthesis

After Sucrase breaks down table sugar into fructose what happens to the enzyme? It remains unchanged nd can be reused to catalyze more reactions.
What pairs a monomer with its polymer? Nucleotides
What is a hydrolysis reaction? when polymers are broken apart in your cells to be used for energy.
