The aerobic system of energy production uses glycogen, but primarily glucose as its energy source.
Glucose is taken in by the cell and broken into pyruvate in the process of glycolysis, the first step in aerobic cell respiration. It takes place in the cell cytoplasm.
Pyruvate is then used in the Krebs cycle in the cell mitochondria in the second step of respiration which produces high energy electron carriers. These high energy electron carries such as NADP are then employed in the electron transport chain, the last step of the respiration process, where a large number of ATP molecules is produced.
By the time the process of aerobic respiration ends, 36 to 38 molecules of ATP are produced from one single molecule of glucose.
Water cycle affects ocean salinity on different levels.
For example, evaporation of ocean water increases the salinity of the ocean, while precipitation and melting of ice decrease it, achieving the balance. Temperature, salinity and water cycle are tightly connected. As global temperatures rises, evaporation increases, and so the salinity. Salty ocean has a tendency to sink. On the other hand warmer ocean rises to the surface and this has influence on ocean currents which then impact the weather.
Answer:
Complete immersion in water is not essential for life for the yabby. If its gills are kept moist (humid air is sufficient), it can absorb oxygen from the air and survive for many days out of water. To breed, however, it must be in water.
The yabby has evolved an ingenious mechanism for surviving drought. As the ground dries up it burrows down following the falling water table, and seals the burrow entrance with an earthen plug. In a small, moist chamber at the bottom, the yabby enters a state resembling suspended animation, its bodily functions (respiration, pulse and digestion) practically ceasing. This mechanism is called aestivation (not hibernation, which is a winter adaptation of warm-blooded animals). The yabby can remain like this for years on end. Burrows well over 5 metres deep have been found.
The yabby is rarely found in clear water. Its natural habitat is usually muddy water, which (although probably not essential to life) may give some protection from predators. Some predators, such as fish, do not depend upon sight alone but can sense pressure changes, tracking their prey even in muddy water; cormorants too can find their prey in muddy waters.
Substrate type is not critically important, although the yabby is commonly found on muddy or silted bottoms with the occasional rock or fallen branch (in contrast to the leaf-littered, rocky or pebbly streams of the spiny crayfishes). Experiments have shown that growth is faster on a natural substrate such as mud or stones, than on an artificial one such as plastic tanks.
