You are a glucose molecule in a disaccharide found in a drink that was sipped by an athlete who is about to begin running a 1600m (1 mile) race. Put the words in the list below in the appropriate order to describe the process of your journey from the mouth and ultimately to the muscle cells for energy.
a. electron transport system
b. active transport

c. stomach

d. pyruvate
e. brush border disaccharidases
f. carbon dioxide and water
g. mouth

h. citric acid cycle
i. glucose transporters
j. duodenum
k. glycolysis

l. jejunum
m. blood
n. esophagus

Answers

Answer:

Mouth -Esophagus-- Stomach -Duodenum -Jejunum -Brush border disaccharidases--Glucose transporters--Active transport--Blood-Glycolysis-Pyruvate--Citric acid cycle - Carbon dioxide and water  : )

Explanation:

The journey of a glucose molecule from the mouth and ultimately to the muscle cells for energy in the correct order is:

Mouth  > Esophagus  > Stomach > Duodenum  > Jejunum  > Brush Border Disaccharidases  > Blood  > Glucose Transporters > Glycolysis  > Pyruvate  > Citric Acid Cycle  > CO2 and Water  > Active Transport  > Electron Transport System.

The drink rich with disaccharides starts its journey from the mouth cavity and moves through the esophagus to the stomach. The disaccharide digestion takes place when it reaches the jejunum through the duodenum of the small intestine by enzyme maltase that also presents in Brush Border Disaccharidases to glucose.

Glucose moves o blood and through a glucose transporter for cellular respiration that starts with glycolysis that converts glucose to pyruvate and enters in TCA cycle and releases CO2 and water as byproducts that ultimately moves to the ETS system to provide energy to the muscles.

Thus, the correct answer is - given above in the correct order.

Why is it possible to do the following party tricks without cheating?
A. Stand with back and heels touching a wall and bend forward from the hips to touch the floor. Return to the upright position without flling or moving the root.
B. Stand facing the edge of an open door with nose and abdomen touching the edge, the feetstraddling the door, and the hands to the sides. Attempt to rise up on the toes.Observe what body motions occur to keep the center of gravity within the base of support whenthese activities are performed without the impediments.

Answers

Answer:

When the body is supported by a wall then it can move in a position counter gravity. The gravity tries to pull the body down and the body responds to it with a slight delay because of wall support.

Explanation:

The body is lifted in upright position with the help of feet. The body rises but after few minutes the gravitational force creates pressure on the body and the body comes down to a natural state. Similarly if the open door is used to perform counter gravity activities then the body will stay for a lesser period in a state because of opened door instead of firm wall support.

what advantage do multicellular organisms have over unicellular organisms?

Answers

Answer:

Explanation:

Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism and it has a large surface area to volume ratio while multicellular organisms use many different cells to function to help it transport enough molecules across it membrane.It has a small surface area to volume ratio!

Here’s your answer

The advantage of a multicellular organism over a unicellular organism is that multicellular organisms can grow to virtually any size because the cells integrate their activities and are permanently associated with one another.

What would you look for under a microscope on a slide with meiotic cells if you wanted to identify metaphase I

Answers

Answer:

This question lacks options, options are: A) A visible nuclear envelope B) Separated sister chromatids at each pole of the cell C) Tetrads lined up at the center of the cell D) A synaptonemal complex E) A cleavage furrow. The correct answer is C.

Explanation:

During Metaphase I, the chromosomes line up at the midpoint or equator between the poles of the cell and are found at their thickest and shortest structure, that is, the tetrads line up at the equator of the cell. They are identified as two double longitudinal sister chromatids. In animals and plants, the chromatids are connected (at their centromeres) to the fusiform apparatus, which has formed between the two centrioles located at the poles of the cell. In many plants, the centrioles are absent. However, the spindle is still present and the plant chromosomes are attached similarly to the microtubule fibers of the spindle.
