Both aerobic and anaerobic respiration yield a net gain of ATP molecules to be used as energy for living things. The processes of _________ would yield the highest number of ATP.
What process releases the least ATP per molecule of glucose for immediate cell use?
Cellular respiration is a three-phase procedure. The phases are called glycolysis, the Krebs cycle, and the Electron Transport Chain. Within these phases is an important molecule called
During bread making, ____________ by yeast produces __________ which makes the bread rise.
alcoholic fermentation, carbon dioxide
What are the reactants of cellular respiration?
Glucose and oxygen.
During aerobic cellular respiration, ___________ combines with hydrogen ions and the product is released as a by-product of respiration.
Cellular respiration allows organisms to release the energy stored in the chemical bonds of glucose, C6H12O6. The energy in glucose is used to produce ATP, which cells use to supply their energy needs. During aerobic cellular respiration, oxygen is reduced and _________ is produced as a by-product of this specific intermediate reaction.
Respiration involves the breakdown of sugar. This process results in the production of energy for the cell. In order for cells to produce the MOST energy, what gas should be present?
Which process changes solar energy into organic matter so that it can be cycled through a food chain?
In the light dependent photosynthetic reactions, light energy is converted into _________ energy, which is stored in molecules like ATP.
Then, in the light independent photosynthetic reactions, this energy is used to convert CO2 into ________.
Plants use carbohydrates to build things such as cellulose. How do plants acquire these building blocks to build mass?
They make carbohydrates through the process of photosynthesis.
Why is oxygen important for all body cells?
It is involved in energy producing cycles.
On average, how many molecules of ATP are gained through the process of aerobic cellular respiration from one glucose molecule?
Both cellular respiration and the burning of fossils fuels release energy. This can be attributed to
the breaking of bonds during oxidation.
______________ is the molecule that feeds the Krebs cycle, our 2nd step in cellular respiration.
