respiration Flashcards
When organism respire, they have what
Metabolic pathways that release energy from organic molecules and capture in ATP
They are respire because of what
Organism need unusable, chemical energy to feel their life processes
Cellular respiration is
Oxidation of organic molecules and release of energy
ATP is
Function
Direct source of energy for cellular metabolism
Transform material, new compound, contract, muscles, removes waste
What is the process of photosynthesis?
Uses light to split H2O and harvest energy electrons in our past to CO2 reducing sugars
What happens in most cells?
Respiration begins in oxidation of glucose to pyruvate chemical reactions called glucoses
What happens in glucolysis
Energy release from glucose molecule to store an ATP
What happens if oxygen is present during glycolysis?
Organisms continue respiration by CO2 chemical reactions of citric acid cycle
What is aerobes
Organisms that use oxygen for respiration beyond glycolysis
As aerobes oxidize acetyl from pyruvate in the citric acid cycle, what happens next?
They store, energy and electron carrier such as an NAD+ plus
What does electron transport chain generate?
It generates proton gradients from energy store in reduce NAD generates proton gradients from energy stored in ATP glycolysis
Anaerobic is
Can live without oxygen, and make even be killed by oxygen in the atmosphere
When anaerobic use glycolysis to reduce via anaerobic is what
Fermentation
Pyruvate is
A product of glycolysis it is to reduce ethanol and lactic acid during fermentation
Magnesium sulfate is
Provides magnesium 2+ a cofactor that activates enzymes of glycolysis
