Answer:
Pyruvate
Explanation:
Glycolysis refers to the pathway through glucose is oxidized to pyruvate.
In glycolysis, a molecule of glucose passes through ten enzyme catalyzed steps to yield two molecules of pyruvate.
Step 1: Glucose is phosphorylated to form glucose-6-phosphate
Step 2: Glucose-6-phosphate is converted to fructose-6-phosphate
Step 3: Fructose-6-phosphate is further phosphorylated to form fructose-1,6-bisphosphate
Step 4: Fructose-1,6-bisphosphate is cleaved into glyceraldehyde-3-phosphate and dihydroxyacetone phosphate
Step 5: Dihydroxyacetone phosphate is converted to another molecule of glyceraldehyde-3-phosphate.
Step 6: Two molecules of Glyceraldehyde-3-phosphate are converted to two molecules of 1,3-bisphosphoglycerate
Step 7: Two molecules of 1,3-bisphosphoglycerate are converted to 3-phosphoglycerate
Step 8: Two molecules of 3-phosphoglycerate are converted to two molecules of 2-phosphoglycerate
Step 9: Two molecules of 2-phosphoglycerate are converted to two molecules of phosphoenolpyruvate
Step 10: Two molecules of phosphoenolpyruvate are converted to two molecules of pyruvate, the end-product of glycolysis.
Therefore, the presence of pyruvate molecules in red blood cells can be used to test for their ability to complete glycolysis
Question: Below is a list of functions performed by organisms. Examine the list, then answer the question that follows.
gas exchange
intake of nutrients
disposal of wastes
stimulus response
reproduction
How do these functions compare between single-celled and multi-celled organisms?
A. Single-celled organisms can perform all of these functions, while multi-celled organisms can perform only some of these functions.
B. Single-celled organisms must perform all of these functions with one cell, while multi-celled organisms can have specialized cells for different functions.
C. Single-celled organisms can perform only some of these functions, while multi-celled organisms can perform all of these functions.
D. Neither single-celled organisms nor multi-celled organisms can perform all of these necessary functions.
Answer:
Option B, Single-celled organisms must perform all of these functions with one cell, while multi-celled organisms can have specialized cells for different functions.
Explanation:
All these functions are performed by both single celled and multi-cellular organism. A single cell has several microscopic organelles that performs specific functions while a multi - celled organism has different body organs/tissues to perform specialized function separately.
A cell exchange gas through the cellular membrane, intake nutrients through engulfing, dispose waste by lysosomes, stimulus response by sensory hairy structure and reproduction through cell division
Hence, option B is correct.
Answer and Explanation:
If the endolymph is mixed with the perilymph then their potassium levels will tend to reach to equilibrium as it is stated that the intermediate membrane have been ruptured. The potassium level will decrease here.
In stereocilia the concentration of the potassium will also tend to reach equilibrium because the membrane is ruptured and the flow of the ions will not remain unidirectional.
The calcium concentration is more in the perilymph as compared to endolymph so the rupturing will allow more calcium ions to get incorporated in the hair vesicles.
The hearing will be affected by mixing of endolymph and perilymph as it will disturb the concentration of various ions and hence the ion channel will be clogged and there will be hearing loss.
Abiotic means is not or never was living.
b. the wind is not a living thing
The growth of the population is described below.
<h3><u>Explanation</u>:</h3>
The population growth of the region is varying according to many factors like,
A. Members of the reproductive age group.
B. Availability of nutrition.
C. Mortality rate of the population.
Here the members of the reproductive age group are few. The population being small in a large area there is a high availability of nutrients.
So the growth rate of the population will be very high. This is called the log phase of the growth.
Then comes the lag phase of growth where the population is considerably big with a fight for food and shelter. The survival of the fittest is seen and the population still grows but slowly. This is the lag phase.
But with time, the population growth is stopped because the ecosystem has a particular carrying capacity which is the maximum number of population that the ecosystem can support. So beyond this, the population won't increase, and thereby the natality rate and the mortality rate becomes equal.
