Answer:
NADH, pyruvate.
Explanation:
The fermentation process occurs in the cytoplasmic matrix.
Thanks to the H+ that are recovered from the oxidation of NADH to NAD +, they bind to pyruvic acid to change its conformation and transform it into lactic acid.
Two types of fermentation occur:
- Lactic
- Alcoholic, which releases ethanol + CO2
This is the reaction:
C6H12O6 + 2 Pi + 2 ADP + 2 NAD → 2 CH3-CH2OH + 2 CO2 + 2 ATP + 2 NAD
Answer:
False. The driving for is the partial pressure gradient of O2 (PO2 difference), not the PCO2 gradient.
However, keep in mind that an increase in PCO2 can facilitate the unbinding of oxygen from hemoglobin. This is due to a decrease in pH associated with PCO2 increase. The H+ ions bind to hemoglobin and decrease it's affinity for oxygen, this is called the bohr effect. But the PCO2 is not the main driving force of oxygen unbinding.
Answer:
Explanation:
There are 206 bones in your body. 26 are in each foot. So the bones of your feet make up just over 25% of the bones in your body.
The correct answers are: All of them.
- Runs off into the ocean;
The parts of the land that are close to the ocean, and are leaned towards it, especially if it is a more rocky landscape, when receiving precipitation, the water runs off directly into the ocean, though this is happening only on a relatively small area.
- Runs off into the streams and rivers;
Most of the precipitation on the land, ends up in the closest streams and rivers which increase their volume and carry the water further downstream.
- Enters the water table of groundwater;
Part of the precipitation managed to get through the soil and the rocks, and enters deeper, eventually reaching the underground reservoirs and filling them, thus contributing to the levels of the groundwater.
- Taken up from shallow soil by plants;
The plants need water for survival, so when there's precipitation, through their roots (some through their leaves), are taking water from the soil, thus spending part of it for their own needs.
