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.

Which of the following is NOT part of the peripheral nervous system?
Ksju [112]

The correct answer is: B. spinal cord  

The nervous system can be divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS). The spinal cord and the brain are part of the CNS, whereas the PNS consists of the nerves that radiate from the CNS to all parts of the body. The PNS includes all neurons that sense and transmit information to the CNS.

The CNS controls thinking processes, movements, and registers the sensations throughout our body. Moreover, the PNS acts to transmit information from the CNS to all parts of the body.

The PNS is in turn divided into two main parts:

1-The Autonomic nervous system (ANS), which regulates involuntary functions and glands. The parasympathetic nervous system is one division of the ANS that controls visceral organs such as glands.

2- Somatic nervous system (SNS), which regulates voluntary muscle movement and transmits information from eyes, ears, and skin to the CNS.

Are wrong because they belong to second part of meiosis(meiosis2). And it is not metaphase1 because metaphase is when the chromatides are lined up in the middle of a cell.
