Phosphatases are a family of enzymes that specifically remove phosphate groups from proteins that were added by protein kinases.

Vanadate is an inhibitor of phosphatases in eukaryotic cells. What effect would vanadate have on the response of cells to signals received by receptor kinases

Answer:

It will increase the cells response longer than the normal duration for response.

Explanation:

Generally phosphorylation by phosphatases  is important to protein structure.it brings about confrontational change in the protein structure, to create protein-protein interaction surfaces. The phosphate ion  in the phosphorylated   protein  regulate the formation of  hydrogen bonds among the amino acids residues in the surrounding  cells.

This brings about a confrontational change in the structure of protein, which enable the substrate to have access to active site of  the enzyme (phospatases),Therefore increasing catalytic actions for phosphorylated process.

Now if Vanadate inhibited phosphatases, phosphorylation of protein will be blocked. Confrontational change in the protein structure will not occur. Hydrogen bonds between  amino acid residues will not be present, thus the essential confrontational change which  create protein-protein interactions for  the cell response from protein kinases will be blocked, thus making cell to take longer time to respond

Therefore it will take longer time for the cell to response to  signals by receptor kinases.

Answer:

The cell response to the signal will last longer than normal.

Explanation:

The enzyme, protein kinases does the opposite of what phosphatases does, they add a phosphate group to a protein. Both these enzymes regulate the protein activity in a cell.

yarga [219]

Answer:

Deposition

Explanation:

Landslides occur under the effect of gravity. When a mass of rock or earth slides down from a mountain or from a cliff then this phenomenon is termed as Landslide.

Landslides are considered to be a rapid method of erosion.  Wind, waves, running water, glaciers and gravity are the five agents of erosion out of which the gravity influences the process of Landslides.

Landslides occur suddenly and are dangerous example of the movement of earth materials under the influence of gravity. When weathered material falls away from a cliff, it slides down under the effect of gravity and finally after reaching the hill, the material gets deposited there. This is called Deposition by landslides.

You are a molecule of phosphorus. Choose a starting point in the process you would go through to move through the entire cycle.
noname [10]

Answer:

First I'd be found in rocks. Erosion would wash me into the soil. Then I'd be absorbed by plants, fungi or microorganisms so they can grow. Animals would get me by eating the plants or drinking the water that eroded the rock. The plants and animals die and I'm absorbed back into the soil.

Explanation:

Phosphorus Cycle Steps

The phosphorus cycle is a slow process, which involves five key steps.

Weathering

Since the main source of phosphorus is found in rocks, the first step of the phosphorus cycle involves the extraction of phosphorus from the rocks by weathering. Weather events, such as rain and other sources of erosion, result in phosphorus being washed into the soil.

Absorption by Plants and Animals

Once in the soil, plants, fungi, and microorganisms are able to absorb phosphorus and grow. In addition, phosphorus can also be washed into the local water systems. Plants can also directly absorb phosphorus from the water and grow. In addition to plants, animals also obtain phosphorus from drinking water and eating plants.

Return to the Environment via Decomposition

When plants and animals die, decomposition results in the return of phosphorus back to the environment via the water or soil.  

Plants and animals in these environments can then use this phosphorus, and step 2 of the cycle is repeated.

Human Impact on the Phosphorus Cycle

Humans have had a significant impact on the phosphorus cycle due to a variety of human activities, such as the use of fertilizer, the distribution of food products, and artificial eutrophication. Fertilizers containing phosphorus add to the phosphorus levels in the soil and are particularly detrimental when such products are washed into local aquatic ecosystems. When phosphorus is added to waters at a rate typically achieved by natural processes, it is referred to as natural eutrophication. A natural supply of phosphorus over time provides nutrients to the water and serves to increase the productivity of that particular ecosystem. However, when foods are shipped from farms to cities, the substantial levels of Phosphorus that is drained into the water systems is called artificial or anthropogenic eutrophication. When levels of phosphorus are too high, the overabundance of plant nutrients serves to drive the excessive growth of algae. However, these algae die or form algae blooms, which are toxic to the plants and animals in the ecosystem. Thus, human activities serve to harm aquatic ecosystems, whenever excess amounts of phosphorus are leached into the water.

murzikaleks [220]

Answer:

Tissue fluid consists of water, ions, and dissolved gases and food substances, which is formed when blood is ultrafiltered from the capillaries into the intercellular spaces. The tissue fluid surrounds the body cells, facilitating the exchange of nutrients and waste materials. It helps bring oxygen and nutrients to cells and to remove waste products from them. As new tissue fluid is made, it replaces older fluid, which drains towards lymph vessels.

Lymph is a colorless fluid containing white blood cells, which bathes the tissues and drains through the lymphatic system into the bloodstream. It is essentially tissue fluid that has entered a lymphatic capillary. Lymph formation depends upon tissue fluid formation.
