|
what are autotrophs?
|
An organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
|
|
|
what is ATP synthase complex?
|
huge molecular complex embedded in the inner membrane of mitochondria
|
|
|
what is a chemical energy?
|
is the potential of a chemical substance to undergo a transformation through a chemical reaction or, to transform other chemical substances
|
|
|
what are examples of Chemical energy?
|
batteries and cells
|
|
|
what are homeotherms?
|
An organism that maintains its body temperature at a constant level, usually above that of the environment, by its metabolic activity
|
|
|
what are poikilotherms?
|
An organism that cannot regulate its body temperature except by behavioral means.
|
|
|
what are heterotherms?
|
is a physiological term for animals that exhibit characteristics of both poikilothermy and homeothermy
|
|
|
what is ATP?
|
considered by biologists to be the energy currency of life. It is the high-energy molecule that stores the energy we need to do just about everything we do.
|
|
|
what is adenosine diphosphate?
|
is an organic molecule involved in the central part of the metabolism of the cell that generates energy.
|
|
|
what is phosphorylation?
|
is the addition of a phosphate (PO4) group to a protein or other organic molecule.
|
|
|
what is the mitochondrion?
|
An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur
|
|
|
what are the three stages of cellular resperation?
|
Glycolysis: the cytoplasm
2) Krebs Cycle/The Citric Acid Cycle: mitochondria 3) Electron Transport Chain: the mitochondria (specifically, the inner mitochondrial membrane) |
|
|
what is the inner membrane?
|
the membrane which separates the chloroplast stroma from the intermembrane space
|
|
|
what is the inter membrane space?
|
The intermembrane space (IMS) is the region between the inner membrane and the outer membrane of a mitochondrion or a chloroplast
|
|
|
what is the matrix?
|
The matrix of a mitochondrion is the mitochondrion internal spaces enclosed by the inner membrane
|
|
|
what is the cristae?
|
are the internal compartments formed by the inner membrane of a mitochondrion.
|
|
|
what is cellular respiration?
|
Cellular Respiration is the process by which cells obtain energy from glucose
|
|
|
what are enzymes?
|
A substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction
|
|
|
what are substrates?
|
basically things that enzymes act upon
|
|
|
what are products?
|
A substance produced during a natural, chemical, or manufacturing process: "waste products".
|
|
|
what is the function of ATP synthase complex?
|
Its function is to convert the energy of protons (H+) moving down their concentration gradient into the synthesis of ATP.
