Chapter 5 (2) Flashcards
Energy
The capacity to do work
Work
When in object is moved again in opposing force
Example, work is done by climbing stairs, add weight increase more work you have to do.
Two types of energy
Kinetic energy, the energy of motion. (Moving)
Potential energy, the energy in object has because of its position (not moving)
Kinetic energy
What are released from a damn, a moving car
Potential energy
What are behind a damn, a compressed spring, When you drop from a higher height.
ATP molecules allows things to break off to do something
Conservation of energy
Convert from one form to another.
Coal, in a car you’re burning gas.
What energy conversions generate heat.
Cellular respiration
The conversion of energy in the cells in mitochondria= ATP
ATP
Adenosine triphospate
1 adenosine + 3 phosphates
They provide the energy for cellular work.
ADP
Adenosine Diphosphate
Released P transfers to another molecule
ATP>adp + p & released energy
ATP requires
Energy from food, breakdown of food releases energy in cellular respiration to make ATP from ADP + P
Energy Coupling
Transfer of energy from processes that yield energy to process that consume energy
Taken from one place to another place
Cellular respiration
Cellular respiration/in mitochondria the function is ATP
Diffusion
Passive transport
Marcuse spread from areas of high concentration to areas of low concentration
Example, perfume, when opening a bottle the closer you are the quicker you smell at the further away you are you smell it a few minutes later
On the top of a slide going down to the ground
No energy is used
Facilitated defusion
Use of transfer proteins in cell membrane to move substances in and out of a cell
Just like diffusion no energy being used
Active transport
Cells must use energy, from area of low concentration to high
The ground up to the slide top, like put in the perfume back in the bottle
