for the following questions, match the labeled component of the cell membrane in the figure with its description. which component is a microfilament (actin filament) of the cytoskeleton?

When cells makes a new compound, such as glycogen from many glucose molecules, usable energy is needed and is obtained by removing a phosphate group from ATP, producing energy plus ADP plus phosphate.

This is referred to as adenosine triphosphate and is the energy currency of the cells.

This is  usually formed from the synthesis of ADP and a phosphate group thereby making it the most appropriate choice.

The mineral-based pigment called Ochre was used by early modern Homo sapiens to color many artifacts and features.

It was used by early modern homo sapiens to color many artifacts and features. This is the most common use by modern humans, especially archaeologists, as any iron rich rock that can be used as a pigment.

The two effects of dividing food-gathering labor, the camp and the dependence of the gender on each other beyond reproduction, were the first great steps toward modern human culture. Sharing of resources and its concomitant division of labor led to a divergence in both the biological and cultural evolution.

The basophilic stippling is a prominent red blood cell, morphologic feature found in lead poisoning (plumbism).

The basophilic stippling is a frequent manifestation of hematologic disease in the peripheral blood, and it is also observable in bone marrow aspirates.

The lead poisoning inhibits the ability to produce hemoglobin by interfering with enzymatic steps in the heme synthesis pathway and reduce red blood cells, which results in the increasing risk of anemia.

The interference of lead in the development of RBCs results as the exposure to a very small amount of lead greatly changes the surface of the red blood cells. The permeability of water gets altered which results in shrinking and so they aren't capable of swelling up like other normal cells.

The hematologic system is involved with lead poisoning where one can find anemia as a result of it.

This drug inhibits the growth of bacterial cells but not human cells. This is an example of the selective toxicity of antibiotics.

Folic acid is an essential component for all cells to synthesize nucleic acids (DNA and RNA). Human cells do not synthesize folic acid and they take it through food. Bacterial cells are impermeable to folic acid and hence they need to synthesize their own folic acid.

Antibiotics target the metabolic pathway of folic acid synthesis in bacteria by inhibiting one of the enzymes in this pathway. These drugs are only toxic to bacteria but not to humans because humans do not have the folic acid synthesis pathway and hence they do not get affected by the action of the antibiotic. This is known as the selective toxicity of antibiotics.

These antibiotics are designed in a way to target the infecting agent (bacteria) while rendering minimal or no toxicity to the host (humans).

Answer: because this has a relation with the food chain of lower levels like herbivores.

Explanation:

as you know plastids are the main source of food production in plants. As they meet the food requirements in plants but animals don't have it so the lower levels like deer who eat grass depend on these plastids of plants to fulfill the need for food and nutrients as animals cant process or made their food. and carnivores fed on these herbivores for their food consumption. so you can indirectly relate this statement to the food chain. and this is how animals depend on plastids found in plants.

By allosteric regulation an enzyme might be activated or inhibited. When a molecule regulates the activity of an enzyme by binding to a site outside of the active site, it is known as an allosteric molecule.

Allosteric regulation occurs when molecules bind to the enzyme on another side, which is not the binding site. This is the allosteric site, and molecules binding to these sites are the allosteric molecules.

Allosteric molecules can be either,

Allosteric inhibition is non-competitive inhibition because the allosteric molecule does not compete directly with the substrate.

It attaches to the enzyme at another site, impeding the substrate to bind the enzyme and turning off its function.

Allosteric activation is a cooperative process in which the enzyme function is enhanced. Some substrates can even work as allosteric activators for other active binding sites.

Allosteric enzymes can change their conformation, exhibiting active and inactive conformations as a result of substrate binding at the activated center and regulatory molecules at other binding sites -allosteric centers-.

According to this framework, When a molecule regulates the activity of an enzyme by binding to a site outside of the active site, it is known as an allosteric molecule.

Postmortem and positron emission tomography have shown that microglial cells play a pathophysiological role in schizophrenia.

We postulated that the previously mentioned glutamatergic impairments in the hippocampus of schizophrenia patients may be related to the microglial synthesis of quinolinic acid (QUIN), an endogenous N-methyl-d-aspartate receptor (NMDAR) agonist. Reduced microglial immunoreactivity for endogenous NMDA receptor agonist quinolinic acid in the hippocampus of schizophrenia patients. We measured the number of QUIN-immunoreactivity microglial cells in the CA1, CA2/3, and dentate gyrus (DG) regions of the posterior hippocampus formation in schizophrenia patients and matched controls. HLA-DR, a popular microglial surface marker, was further immunostained in nearby histological sections. In the CA1 hippocampus sub region of schizophrenia patients compared to controls, fewer QUIN-immunoreactivity microglial cells were seen (left p=0.028, right p=0.018). In the CA2/3 and DG areas, no notable diagnosis-dependent alterations were seen. Potential confounding factors such as age, disease duration, autolysis time, psychotropic medication, and hippocampus volume were taken into account while analyzing these results. There were no variations in the overall density of microglial cells linked to diagnosis (HLA-DR expression). Our results imply that schizophrenia is related with decreased microglial QIUN content in the hippocampus CA1 region. We surmise that this connection could be a factor in schizophrenia patients' hippocampus' decreased glutamatergic neurotransmission.

Ca2 is re-sequestered into the sarcoplasmic reticulum during the relaxation period by Ca2+ ATPase.

Similar to the smooth endoplasmic reticulum in other cells, the sarcoplasmic reticulum (SR) is a membrane-bound structure found in muscle cells. The SR's primary job is to hold calcium ions (Ca2+). The concentration of calcium ions within a cell is 10,000 times lower than the concentration of calcium ions outside the cell, ensuring that calcium ion levels are kept relatively constant.

The sarcolemmal network or the t-tubular network is peripherally coupled with jSR paperwork. Rows of proteins referred to as "feet" are seen between the 2 membranes in peripheral connections where the jSR profile coincides with the sarcolemma or t-tubule.
