The net energy yield from this pathway, where glucose is broken down through several steps forming pyruvate, is ________ molecul
stepan [7]

Answer:

2 molecules of ATP and 2 molecules of NADH

Explanation:

Glycolysis is the first step of cellular respiration (break down of glucose to extract energy) which occurs in the cytoplasm. Glycolysis is a pathway common to all living organisms- prokaryotes and eukaryotes, as it does not require oxygen to occur.

Glycolysis occurs in two major phases (ten steps) requiring 10 enzymes catalyzing each step; the energy-requiring phase and the energy-requiring phase.

In the energy-requiring phase, the starting molecule (glucose) gets rearranged in a series of chemical reactions, and two phosphate groups gets attached to it producing fructose-1,6-bisphosphate which is unstable, This modified sugar then splits in half due to its instability to form two different but inter-convertible phosphate-bearing three-carbon sugars (Dihydroxyacetonephosphate, DHAP and Glyceraldehyde-3-phosphate, G3P). Because the phosphates used in these steps come from 2 ATP molecules, 2 ATP molecules get used up in this phase

All the DHAP molecules get converted to G-3-P in order to enter the next phase.

In the energy-recovering phase, the 3-carbon sugar (G3P) is converted into another three-carbon molecule called pyruvate, through a series of reactions. In these reactions, two ATP and 1 NADH molecules are made. This recovery phase occurs twice (one for each of the two isomeric three-carbon sugars, DHAP and G3P). Hence, a total of 4 ATP and 2 NADH molecules are produced in this phase.

Overall, Glycolysis converts one glucose (six-carbon) molecule to two pyruvate (three-carbon) molecules and a net release of 2 ATP molecules (4 overall - 2 used) and 2 NADH molecules.

You own a winery in Napa Valley. An assistant accidentally leaves the lid for a vat of wine slightly ajar. Would the yeast insid
anastassius [24]

<span>When the lid for a vat of wine is slightly open, the yeast inside can continue to perform alcoholic fermentation because the carbon dioxide produced by the yeast during fermentation will act as a blanket over the wine.  Nevertheless, the air around the fermenter must be still and enough carbon dioxide should be produced to continue alcoholic fermentation. However, at some point, carbon dioxide will fall and can no longer protect the wine. This is the right time to get your wine covered before it will be vulnerable to undesirable microorganisms. </span>

Therefore, open fermentation is good in the early stages of fermentation because yeast need oxygen to synthesize sterols and assimilate fatty acids to ensure the nutrients it needs to multiply and ferment the 70% of the sugar from the fruit. Furthermore, the yeast is responsible in decomposing sugar from the grapes into alcohol and carbon dioxide.

How long do meps urinalysis results take?
Ksivusya [100]

The urinalysis results for Military Entrance Processing Station (MEPS) are usually available within 72 hours. However, sometimes it will be ready in as little as 24 hours. When something is revealed in the test results, the system flags it for further review by the authorized command officials.

Part 1: Cats Falling Out of Windows
xenn [34]

The way that the number of injuries per cat relate to the number of stories a cat falls is that:

  • As we examine the data about cats dropping from a given number of stories, a tendency becomes obvious. The cat sustains more wounds from story one to story eight than in the previous stories combined. Despite the fact that there are fewer injuries in the last category.

<h3>Why do cats survive after jumping off of a tall building?</h3>

High-rise syndrome describes the wounds that cats can get when they fall from a steep height, like an inside second-floor landing or balcony, out a window, down a fire escape, or when they fail to jump from a landing to a higher architectural element, like a ledge or window.

Cats may live comfortably in apartments and high-rise buildings, but we must make sure they have enough stimulation and playtime.

Therefore, According to Jim Usherwood of the Royal Veterinary College's structure and motion lab, stated that cats have long, flexible legs. "They have respectable muscle mass. Since they can jump rather well, the same muscles focus their efforts on slowing down rather than shattering bones."
