In the pentose phosphate shunt, glucose 6-phosphate is oxidized to 6-phosphogluconate, which is then decarboxylated to ribulose

5-phosphate. What is the main metabolic role of this pathway?

Answer:

This pathway is essential for other biosynthetic pathways using NADPH

Explanation:

Glucose 6-phosphate can be metabolized by both the pentose phosphate pathway and the glycolytic pathway, however the path chosen depends on the concentration of the NADP+ with in the cytoplasm.  

There are two phases of this cycle – a) oxidative phase – NADPH is formed

And b) Non oxidative – formation of 5 carbon sugar.  

This pathway fulfills the need of NADPH  for further usage in reductive biosynthesis. Also the 5 carbon sugar is used in the production of nucleotides. It further converts the excess 5 carbon sugar into intermediate molecules required in the glycolytic pathway

Answer:

The pentose phosphate is also known as the phosphogluconate pathway that links the different metabolic reaction with each other and runs in addition or parallel with the glycolysis. This is a type of anabolic reaction occur in the cell.

The main metabolic role of this way is the production of large number of NADPH. The intermediate Erythrose 4-phosphate of this pathway is used for the synthesis of the aromatic acid synthesis. The glycerol 3-phosphate is used for the production of ATP. The Ribose 5-phosphate is used as a precursor for the nucleic acid biosynthesis.

Answer:

The ability of flight allows them to migrate to different plants if needed. They can only leave a plant and walk away if there is a predator or if their food source's quality has deteriorated, otherwise they remain on their original host plant until then.

lisov135 [29]

Answer:

1. Hematoma is an open injury that occurs whenever a large blood vessel is damaged and bleeds rapidly. False

2. You should never remove an avulsion skin flap, regardless of its size. True

3. When possible, ALS providers should administer IV fluid within 3 minutes after the crushing object is lifted off the body. False

Explanation:

1. It is false because, although is true that a hematoma occurs when you have a large blood vessel damaged, i t is a closed injury, not an open one.

2. It is true, you should never remove an avulsion skin flap, regardless of its size. The avulsion may have a serious infection.

3. It is false  because ALS providers should administer IV fluid before the crushing object is lifted off the body.

Which pair of organelles works together to give structure and support in animal cells?
Montano1993 [528]

Answer:

Cell membrane and cytoskeleton

Explanation:

The cell membrane is the outer covering that encloses the cell contents and regulates movement of materials in and out of the cell. the cell membrane gives the cell its structure. Cytoskeleton provides support to the cell and  include three types of small networks:

Actin filaments: - are flexible double strands of the protein actin . They lead the intracellular movement of organelles  and molecules  and stabilize mechanically the plasma membrane .

Microtubule: - are rigid hollow cylinders of the proteins α- & β-tubulin

They are responsible for the position and stability of ER and  Golgi-Apparatus , help to divide & move chromosomes during mitosis  and organize the growth of the cell wall .

Intermediate filaments: - are robe like fibres of different proteins which give

mechanical support

Memory can be improved by using a variety of techniques. Describe each of the techniques listed below and explain its use throug
Aliun [14]

Answer: EDG

Explanation:

First, effortful processing is encoding that requires attention and conscious effort. This would be something like studying where you store facts in your mind for use later. Automatic processing on the other hand, is unconscious encoding of incidental information and of well-learned information. For example, I know what someone means immediately if they say it's noon. As for chunking, it is organizing items into familiar, manageable units. One perfect example would be my phone number. There are many different numbers, but its easier to manage when some are grouped together. Then there are mnemonics which are memory aids, especially those techniques that use vivid imagery and organizational devices. For example, I use the first letter technique (PEMDAS) to help me when solving math problems. Spaced or distributed practice is studying or processing with breaks to help understand concepts. For example, when I study, I take a five minute break every 20 minutes to help my brain cool down and be ready to learn more. Now, deep processing involves elaboration rehearsal which involves a more meaningful analysis. For example, giving meaning to different words or images and making them relatable.
