Flashcards in Chapter 6- Cellular Respiration Deck (15):
When there is enough oxygen reaching your cells to support the energy needs.
Plants convert energy of sunlight to the chemical energy of sugars and other molecules.
Self feeders- make their own food; they don't need to eat to gain energy to power their cellular processes. organisms that make all their own organic matter- including carbohydrates, lipids, proteins, and nuclei acids- from nutrients that are entirely inorganic: carbon dioxide from air and water minerals from the soil.
Other feeders: we must eat organic material to get our nutrients and provide energy for life's processes. organisms that cannot make organic molecules from inorganic ones.
Most ecosystems that depend on photosynthesis for food.
They obtain their food by eating plants or by eating animals that have eaten plants
The aerobic harvesting of chemical energy from organic fuel molecules
A molecule of glucose is split into two molecules of a compound called purification acid
Citric acid cycle
Completed the breakdown of glucose all the way to CO2 j
Acts as a shuttle carrying high-energy electrons from one area of the cell to another
Electrons captures from food by the NADH formed in the first two stages are stripped of their energy, a little bit at a time, until they are finally combined with oxygen to form water.
3 stages of cellular respiration
Stage 1: glycolysis
Stage 2: the citric acid cycle
Stage 3: electron transport
Electron transport chain
A series of electron carrier molecules that shuttle electrons during the final stage of cellular respiration, ultimately using the energy of the electrons to make ATP
Without oxygen ; harvest of food energy is called fermentation
