Heterotrophs |
It is an organism that cannot fix carbon and uses organic carbon for growth. |
Heterotrophs uses organic carbon for growth. |
|
Autotrophs |
An organism that produces complex organic compounds from simple substances present in its surroundings. |
Autotrophs produces complex organic compounds. |
|
Photoautotrophs |
An organism, typically a plant, obtaining energy from sunlight as its source of energy. |
Photoautotrophs obtain energy from sunlight. |
|
Chemoautotrophs |
An organism that obtains energy through chemical process. |
Chemoautotrophs obtains energy through chemical reactions. |
|
Cell respiration |
Both autotrophs and heterotrophs carry out chemical reactions that release the free energy of organic compounds. |
Cell respiration release free energy of organic compounds. |
|
Producers |
Autotrophs, which produce food other organisms use. |
Producers make food that consumers use to make energy. |
|
Consumers |
Heterotrophs consume plants and other organisms for food. |
Consumers consume things that producers made. |
|
Decomposers |
Bacteria, fungi, and other heterotrophs that break down and use dead plants and animals for food. |
Decomposers get energy from dead plants and animals. Ex)mushroom. |
|
Biotic |
Produced by life or living organisms. |
Biotic is produced by living organisms. |
|
Abiotic |
Nonliving, which is a nonliving physical and chemical attribute of a system. |
Abiotic is contrast to biotic. ( nonliving) |
|
Ecosystem |
The biotic and abiotic components of a particular place make up an ecosystem. |
Ecosystem always rotate. Abiotic+Biotic |
|
Habitats |
Places where particular organisms live. |
Habitat is where organisms live. |
|
Biosphere |
It contains many ecosystems. |
Coral reefs, deserts, marshes,a d forests. |
|
Energy |
Energy is often stored by cells in biomolecules. |
Energy is necessary to our life. |
|
Chemical energy |
Organisms store energy in the organic molecules from which the organisms are made. |
We use chemical energy to live. |
|
Free energy |
The portion of the chemical energy that is available to do work. |
Free energy is a type of chemical energy. |
|
Heat energy |
A form of energy which transfers among particles in a substance. |
Heat energy is related to temperature. |
|
First law of thermodynamics |
Energy cannot be created or destroyed. |
Energy cannot be destroyed or created. |
|
Second law of thermodynamics |
Systems tend to change in a way that increases the disorder. |
It tends to change a way that increases the disorder. |
|
Entropy |
Systems tend to change in a way that increases the disorder. |
Entropy= disorder. |
|
Enzymes |
All living cells contain specialized proteins. |
Enzymes are type of proteins. |
|
Actives site |
Specific reaction catalyzed by an enzyme depends on a small area of its tertiary structure. |
Actives site is a part of tertiary structure. |
|
Substrate |
The close fit of the starting molecules. |
Substrate= close fit of the starting molecules. |
|
Metabolism |
All the chemical activities and changes that take place in a cell or an organism. |
Metabolism is all the chemical activities. |
|
Synthesis |
Building of reactions. |
Synthesis=reactions. |
|
Decomposition |
Breaking down reactions. |
Decomposition= breaking down. |
|
Biosynthesis |
Consumes free energy. |
Biosynthesis... Use free energy. |
|
Oxidation |
Certain bonds are broken and rearranged. |
Oxidation - broken and rearrange. |
|
ATP |
Adenosine triphosphate. |
ATP energy that is produced after chemical reaction. |
|
Digestion |
The processes that break down food are known collectively |
We digest food by using all chemical reactions and organs. |
|
Pepsin |
Active protein- digesting enzyme |
Pepsin= active protein. |
|
Small intestines |
They absorb energy from foods that we eat. |
It is 6m long. |
|
Salivary amylase |
Carbohydrate digestion begins in the mouth with the action of an enzyme. |
It is in our mouth. It helps us digest our food. |
|
Lipase |
Fat-digesting enzyme. |
Enzyme that helps you digest fat. |
|
Villi |
The surface area of the intestinal lining is increased tremendously by millions of small fingerlike projections. |
Fingerlike projections. It's in the small intestine. |
