Answer:

Transitional epithelium

Explanation:

Transitional epithelium consists of a epithelial cells that are arranged in a stratified manner or in multiple layers, which gives the cells a structure or ability to change shape. He epithelium tissues n contract and expand as a result of the arrangement of the cells. The cells are connected by junctional complexes.

The transitional epithelium is found in the organs of the urinary system, especially in the urinary bladder, ureters, and urethra. The transitional epithelium found in the urinary system functions in giving protection, allowing the organ to contract and expand, and also to withstand osmotic pressure.

How many atp equivalents are consumed in the conversion of each of the following to a glucosyl residue in glycogen?

Nina [5.8K]

<h3><u>Answer;</u></h3>

Dihydroxyacetone phosphate - 1

Fructose-1,6-bisphosphate - 1

Pyruvate - 13

G-6-P - 1

<h3><u>Explanation;</u></h3>

1) Dihydroxyacetone phosphate = 1

G1P + GTP --> UDPG + PPi two P is equivalent to 2 ATP --->2 ADP + Pi) Therefore, two ATP equivalents - but UDP is the product and only one P needed

2 DHAP --> F1,6-BP -->F6P --> G6P -->G1P -->UDPG --> glucosyl residue

2) Fructose 1,6-bisphosphate = 1

3) Pyruvate = 13

2 pyr + 2 ATP --> 2 OAA

2 OAA + 2 GTP --> 2 PEP

2 PEP --> 2 2PG --> 2 3PG

2 3PG + 2 ATP --> 2 1,3 BPG

2 1,3 BPG + 2 NADH --> 2 G3P

2 NADH = 6 ATP

2 G3P --> DHP + G3P --> FDP -- > F6P + P

F6P --> G6P --> G1P

G1P + UTP --> UDPG + PP

4) Glucose-6-phosphate = 1

G6P -->G1P G1P + UTP --> UDP-GLC + 2 Pi

UDP-Glc + glycogen --> glycogen+ 1 Glc

Why does the glass jar fail to function as a rib cage in the breathing mechanism

GaryK [48]

Answer: The model, which is air tight, represents the thorax, and air is only able to enter via the glass tube which represents the trachea.

As the rubber sheet is pulled down the volume of the jar increases, the pressure therefore decreases and air is drawn in through the glass tube inflating the balloons, which represent the lungs.

There are a number of similarities and differences between the model and the actual respiratory system.

Glass tube/tracheaAllows air to pass through, splits into twoGlass is rigid and inflexible unlike the cartilage bound trachea

Bell jar/chest cavityAir tightUnable to move, the ribs can move up and out to increase the volume of the thorax

Balloons/lungsCan inflate and deflate, are elastic like the alveoliThe balloons are large open spaces whereas the lungs are made up of millions of individual elastic alveoli

Rubber sheet/diaphragmCan be domed up to decrease the volume in the jarThe diaphragm only flattens, it is not pulled downwards like the rubber sheet.
