Answer:
alveoli
Explanation:
They are the smallest structures in our lungs where capillaries exchange O2 and CO2 in blood.
Answer:
In lactic acid fermentation, pyruvate is reduced to lactic acid. ... In alcoholic fermentation, pyruvate is reduced to alcohol and releases carbon dioxide. This type of fermentation is commonly used with yeast to make alcoholic beverages and cause bread to rise.
Explanation:
Answer:
active transport, like Na + ions leaving the cell
Explanation:
The active transport requires an energy expenditure to transport the molecule from one side of the membrane to the other, but the active transport is the only one that can transport molecules against a concentration gradient, just as the diffusion facilitated the active transport is limited by the number of transport proteins present.
Two major categories of active, primary and secondary transport are of interest. The primary active transport uses energy (generally obtained from ATP hydrolysis), at the level of the same membrane protein producing a conformational change that results in the transport of a molecule through the protein.
The best known example is the Na + / K + pump. The Na + / K + pump performs a countertransport ("antyport") transports K + into the cell and Na + outside it, at the same time, spending on the ATP process.
The secondary active transport uses energy to establish a gradient across the cell membrane, and then uses that gradient to transport a molecule of interest against its concentration gradient.
Extinction of species reduces the number of different species in ecosystems, hence lowering the diversity of living things.
<span>All the animals mentioned [monkey, fish, star fish, clam gecko] have endoskeleton except grasshopper which has exoskeleton. Endoskeleton is an internalised skeleton which is found inside the body of the animals which possess it while exoskeleton is a type of skeleton that is found outside the body.</span>
