|
What is the definition of energy? |
The capacity to do work. |
|
|
|
What is thermodynamics? |
The study of energy. |
|
|
|
What is the definition of potential energy? |
The energy an object has due to location OR structure. |
|
|
|
What is the definition of kinetic energy? |
The energy of motion. |
|
|
|
Where is potential energy stored? What happens when you break a bond of ATP? |
Potential energy is stored in the bonds that hold atoms together into molecules. Breaking a bond of ATP releases energy that can be used for other processes. |
|
|
|
Can energy be destroyed or created? |
No. Energy can be converted but never created or destroyed. |
|
|
|
What is heat a by-product of? |
Heat is a by-product of energy product of energy conversion. |
|
|
|
What is lost at each conversion of energy? |
At each conversion of energy, some energy is lost in living things in the form of heat. |
|
|
|
What is the definition of entropy? |
The amount of disorders in a system. |
|
|
|
How does a disorder in a system increase? |
With each energy conversion, heat is released, so the disorder in the system increases. |
|
|
|
What are producers? |
They absorb the sun's energy, convert it into chemical energy, and make their own food. |
|
|
|
Where does photosynthesis happen? |
It happens in the chloroplasts. |
|
|
|
How do consumers obtain energy? |
They consume producers. |
|
|
|
What is cellular respiration? |
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into ATP |
|
|
|
Simple definition of ATP. |
Take sugars and make ATP |
|
|
|
What is used in cellular respiration to harvest energy? |
In cell. resp., oxygen is used to harvest the energy stored in sugar. |
Ana- (build up) |
|
|
Describe anabolic. |
To build up. Small molecules are built into larger ones. *ENERGY IS REQUIRED* |
Cata- (to break down) |
|
|
Describe catabolic. |
To break down. Large molecules break down into smaller ones. *ENERGY IS RELEASED* |
|
