Answer: Option A
Explanation:
Kinesin -1 is the major anterograde motor which helps in the transportation along micro tubules. This is important for the proper transport of the mitochondria, Golgi derived vesicles, endoplasmic reticulum tubulin, mRNA and intermediate filament sub units.
It moves along the micro tubules and for this task it gets energy from the adenosine triphosphate.
The heavy chain of KInesin 1 is made of globular head via short flexible neck and has a light chain as well which ends in the carboxy terminal.
D
Cos Dna contains deoxyribose, Rna ribose
Answer:
First, it's important to get clear on the meaning of Homeostasis.
In simple terms, it refers to the capacity of a living thing (plant or animal) to react or behave in such a way that enables it to continue to survive irrespective of changes in its immediate environment.
Explanation:
In humans, the body has a system which reacts to the external stimuli of temprature. When the weather is hot, the brain through a sequence of electrical and chemical signals tells the skin to open up the pore, then we experience venting of sweating which cools the body and regulates internal heat. This is an instance of homeostasis.
This does not mean that the plant or animal is completely immune to such external changes.
In the case of the tomato plant, the hair on the leaves and stem of the plant is an example of Homeostatic responses which have evolved over the years to discourage predators such as the hornworm caterpillar from defoliating the plant.
Cheers!
Answer:
Both store materials needed by the organism.
Explanation:
Proteins and carbohydrates are two biomolecules present in living organisms. They perform varying functions in the body of an organism. According to this question, a specific protein (ferritin) and carbohydrate (glycogen) is described.
Ferritin is a protein molecule containing Iron (Fe). Iron is needed by living organisms as it plays a vital role in organism's metabolism. On the other hand, glycogen is a carbohydrate molecule that is made up of glucose molecules, needed by living organisms.
Based on the description of the two biomolecules provided, they are similar in their primary functions for an organism in the sense that THEY BOTH STORE MATERIALS (glucose and iron) NEEDED BY AN ORGANISM.
Answer: feed-back
When the product of a metabolic pathway accumulates, it may be able to slow down or turn off the pathway by inhibiting the activity of an enzyme that catalyzes an early step in the pathway. This is referred to as feed-back inhibition.
Explanation:
Feed-back inhibition is said to occur when the final product of a biochemical pathway signal the inactivation of the starting materials of the pathway.
For example: when pyruvate signal the inactivation of phosphofructokinase, the glycolytic pathway gets turned off.
