Streptococci are coccoid bacterial cells, and when the Gram staining technique is used, they show up as purple (Gram-positive) stains. They do not produce spores and are not mobile.

These cocci have a diameter of between 0.5 and 2 m. Streptococcus species cell division is described as. These bacteria multiply in pairs or chains along a single axis or plane.

Blood agar is often incubated at 35–37 °C for 18–24 hours to produce colonies that are typically grayish-white, smooth, glossy, and translucent with areas of hemolysis or no hemolysis.

Many species of Streptococcus induce hemolysis, which is characterized by a partial breakdown of the red blood cells (RBCs) in the medium and is visible as a green zone encircling the colony due to hemoglobin coloring in RBCs.

What are thylakoid membrane?

The thylakoid membrane is site of photochemical and electron transport reactions of oxygenic photosynthesis.

Photosynthesis takes place in the two distinct stages.

In light reactions, energy from the sunlight drives the synthesis of ATP and NADPH, coupled to formation of O2 from H2O.

In the dark reactions, so named because they do not require sunlight, the ATP and NADPH produced by light reactions drive glucose synthesis.

The thing unusual about the process is that Photosynthesis produces A T P and N A D P H.

What is photosynthesis?

Plants, algae, and some microbes convert sunlight into energy through a process called photosynthesis. The procedure chemically transforms water and carbon dioxide (CO2) into food (sugars) and oxygen. Chlorophyll, the pigment that gives plants their green color, is frequently a key component of the chemical reaction.

The two separate stages of photosynthesis occur.

Energy from sunlight powers the synthesis of ATP and NADPH in light processes, along with the oxidation of water to produce oxygen (O2).Because they don't require sunlight, the dark reactions are so-called because they utilise the ATP and NADPH generated by light reactions to power the synthesis of glucose.

Chemiosmosis is characterized by a significant buildup of h between the inner and outer mitochondrial membranes.

Protons, also known as hydrogen ions, will diffuse from an area with a high proton concentration to an area with a low proton concentration. Using an electrochemical gradient of protons across a membrane, ATP can be produced. The term "chemiosmosis" refers to a process that is similar to osmosis in that it involves the passage of water across a selective membrane.By means of chemiosmosis, ATP is produced by the enzyme ATP synthase. In order to create ATP, it phosphorylates adenosine diphosphate (ADP) by using the free energy difference created by protons passing across the membrane. In mitochondria and chloroplasts, as well as in the majority of bacteria and archaea, ATP is produced by chemiosmosis. For instance, during photosynthesis, an electron transport chain in the stroma (fluid) of chloroplasts pumps H+ ions (protons) into the thylakoid gaps across the membrane. As protons travel through ATP synthase, the energy that has been saved is used to photo-phosphorylate ADP, creating ATP.

A stimulus first causes sodium channels to open. Since there are a lot more sodium particles outwardly, and within the neuron is negative compared with the outside, sodium particles hurry into the neuron.

Sodium has a positive charge, so the neuron turns out to be more sure and becomes depolarized. It takes more time for potassium channels to open. At the point when they do open, potassium surges out of the cell, turning around depolarization. Likewise, at about this time, sodium channels begin to close. This makes the activity expected to return toward - 70 mV (repolarization).
