During the split-brain procedure, epilepsy patients’ corpus callosums were severed, which allowed the two hemispheres of the brain to communicate with each other.

The split-brain procedure was used by researchers to study how each hemisphere of the brain contributes to different cognitive and motor functions. In this procedure, the corpus callosum, a band of neural fibers that connects the two hemispheres of the brain, is severed. This disconnects the communication between the two hemispheres of the brain and allows each hemisphere to operate independently.

The researchers used this procedure on epilepsy patients to study how the two hemispheres of the brain process information. Epilepsy is a neurological condition characterized by seizures, which can often be localized in one hemisphere of the brain. To treat these seizures, surgeons would sometimes perform the split-brain procedure in an attempt to isolate the affected hemisphere.

During the procedure, the corpus callosum is severed, which is effective in reducing the frequency and severity of seizures in some cases. After the procedure, researchers tested the patients' abilities and found that each hemisphere has its own specialized functions.

The highest reaction rate of cellulose enzyme is at temperature 60 degrees Celcius.

Explanation:

There are some factors that influence the enzyme activity.

1. Temperature

2. pH

3. substrate concentration

4. enzyme concentration

In the beginning, the enzyme (cellulose) is in inactive condition. It can be seen from the low amount of gas produced.

As the temperature increase, the enzyme start reacting by binding more substrate (cellulose) and releasing more product (methane). In human cell, mostly enzyme can work best at optimum temperature around 40 degrees Celcius, while in bacteria may exceed this. Based on the graph shown, the enzyme perform very well at 60 degrees Celcius since the gas produced reach the highest amount, is 5 ml.

As temperature level higher than its optimum, the reaction rate decrease since the enzyme which is made of protein start denaturating. In this condition, enzyme unable to react with the substrate as well as produce a product anymore.

In conclusion, the highest reaction rate of cellulose enzyme is at temperature 60 degrees Celcius.

Answer:

All viruses depend on cells for reproduction and metabolic processes. By themselves, viruses do not encode for all of the enzymes necessary for viral replication. But within a host cell, a virus can commandeer cellular machinery to produce more viral particles. Bacteriophages replicate only in the cytoplasm, since prokaryotic cells do not have a nucleus or organelles. In eukaryotic cells, most DNA viruses can replicate inside the nucleus, with an exception observed in the large DNA viruses, such as the poxviruses, that can replicate in the cytoplasm. RNA viruses that infect animal cells often replicate in the cytoplasm.

The Life Cycle of Viruses with Prokaryote Hosts

The life cycle of bacteriophages has been a good model for understanding how viruses affect the cells they infect, since similar processes have been observed for eukaryotic viruses, which can cause immediate death of the cell or establish a latent or chronic infection. Virulent phages typically lead to the death of the cell through cell lysis. Temperate phages, on the other hand, can become part of a host chromosome and are replicated with the cell genome until such time as they are induced to make newly assembled viruses, or progeny viruses.

The Lytic Cycle

During the lytic cycle of virulent phage, the bacteriophage takes over the cell, reproduces new phages, and destroys the cell. T-even phage is a good example of a well-characterized class of virulent phages. There are five stages in the bacteriophage lytic cycle (see Figure 1). Attachment is the first stage in the infection process in which the phage interacts with specific bacterial surface receptors (e.g., lipopolysaccharides and OmpC protein on host surfaces). Most phages have a narrow host range and may infect one species of bacteria or one strain within a species. This unique recognition can be exploited for targeted treatment of bacterial infection by phage therapy or for phage typing to identify unique bacterial subspecies or strains. The second stage of infection is entry or penetration. This occurs through contraction of the tail sheath, which acts like a hypodermic needle to inject the viral genome through the cell wall and membrane. The phage head and remaining components remain outside the bacteria.

This figure outlines the stages of the lytic cycle. Step 1 is attachment when the phage attaches to the surface of the host. The bacteriophage is shown sitting on the surface of the bacterial host cell. Step 2 is penetration when the viral DNA enters the host cell. The image shows DNA from within the virus being injected into the host DNA. Step 3 is biosynthesis when the phage DNA replicates and the phage proteins are made. The image shows various pieces of virus being built within the cell. Step 4 is maturation when the new phage particles are assembled. This shows the viral components being put together in the cell. The fifth step is lysis when the cell lyses and the newly made phages are released. This shows the cell bursting and built viruses being released.

Figure 1. A virulent phage shows only the lytic cycle pictured here. In the lytic cycle, the phage replicates and lyses the host cell.

The third stage of infection is biosynthesis of new viral components. After entering the host cell, the virus synthesizes virus-encoded endonucleases to degrade the bacterial chromosome. It then hijacks the host cell to replicate, transcribe, and translate the necessary viral components (capsomeres, sheath, base plates, tail fibers, and viral enzymes) for the assembly of new viruses. Polymerase genes are usually expressed early in the cycle, while capsid and tail proteins are expressed later. During the maturation phase, new virions are created. To liberate free phages, the bacterial cell wall is disrupted by phage proteins such as holin or lysozyme. The final stage is release. Mature viruses burst out of the host cell in a process called lysis and the progeny viruses are liberated into the environment to infect new cells.

Cumulative effect of stress and toxins, causing the cellular damage first and eventually death of cells is called as oxidative stress.

Oxidative stress occurs when there exists an imbalance between  production of reactive oxygen species (ROS) and body's ability to detoxify or repair the resulting damage. ROS are molecules containing oxygen with an unpaired electron, making them highly reactive and potentially damaging to cellular components, such as proteins, lipids, and DNA.

To prevent oxidative stress, our body has a defense system, including antioxidants and enzymes, that neutralizes and removes these harmful molecules.

However, when the production of ROS exceeds the body's ability to eliminate them, oxidative stress occurs, leading to cellular damage and, ultimately, cell death. This can contribute to the development of various diseases, including cancer, cardiovascular disease, and neurodegenerative disorders.
