Time changes by one hour for each 15° degree change in longitude; this is because

This is because twenty-four latitude lines were chosen so that 24 hours represents a 360 revolution around the planet. As earth spins on its axis, different places receive sunlight at different times. Each day goes from morning to night as earth turns because the earth spins from west to east therefore the day moves from east to west. Lines of longitude help us keep track of time differences from place to place. Mapmakers divided earths 360 degrees of longitude by 24 hours which results to 15, the time changes by one hour every 15 degrees. It is one hour earlier every 15 degrees of longitude to the west and it is one hour later every 15 degrees of longitude to the east.

Can you please tell me an explanation of what happens during the prophase stage of mitosis?

arsen [322]

Prophase is the first step in mitosis and many changes occur. Chromatin fibers become coiled into chromosomes, with each chromosome having 2 chromatids joined at a centromere. The mitosis spindle, composed of microtubules and proteins, form in the cytoplasm.

What is a red tide ?

netineya [11]

Red tide is a common name for algal blooms, which are large concentrations of aquatic microorganisms, such as protozoans and unicellular algae.

The upwelling of nutrients from the sea floor, often following massive storms, provides for the algae and triggers bloom events

Much of the regulation of gluconeogenesis is a result of the inhibition of?

matrenka [14]

The suppression of glycolysis is responsible for a large portion of the control of gluconeogenesis.

Discussion about the statement:

The cytosol is the site of all glycolysis and gluconeogenesis processes. The rate at which glucose is produced in the body is inversely related to the intake of carbohydrates. The suppression of glycolysis is responsible for a large portion of the control of gluconeogenesis.

Fructose 2,6-bisphosphate is an intermediate that plays a crucial role in controlling both glycolysis and gluconeogenesis. This metabolite's presence can promote glycolysis and prevent gluconeogenesis.

Control of Gluconeogenesis and Glycolysis

At various crucial stages of glycolysis and gluconeogenesis, metabolic control takes place. The catalysts that accelerate each of these stages can be activated or inhibited by outside forces, for example, the quantity of a molecule that comes after. The conversion of glucose and ATP into glucose 6-phosphate is the first controlled step in glycolysis. Keep in mind that hexokinase catalyzes this process.

High levels of blood glucose, AMP, and low levels of cellular ATP all trigger the activation of hexokinase. In other words, the glycolysis process is enhanced when blood glucose levels are high. Whenever cellular ATP levels are low and AMP levels are high, glycolysis is also increased. Both of these instances show that the cell is short on energy and may be directly influenced to create additional energy.
