What is an organelle
Setler [38]

Good afternoon. An organelle is any structure in cells that has a specialized function. They are usually found in eukaryotic (nucleus) cells. They help with energy, making proteins, and removing wastes from a certain area. They are composed of large molecules such as proteins, carbohydrates, lipids, and nucleic acids. I hope I helped!! If you have any more questions then don't hesitate to let me know. Have a great day!!

Climate characterized by mild temperatures is ______. Question 4 options: tropical humid dense temperate
Pachacha [2.7K]

The correct answer is - temperate.

The temperate climates can simply be described as climates with milder temperatures. These climates have changes of seasons, four of them, spring, summer, autumn, and winter. The springs and autumns tend to have mild temperatures, the summers are warm, and the winters are cold, but the highest and lowest temperatures do not come close to the extremely high temperatures in the tropical zone, or extremely low temperatures in the high latitude zones. So these climates have temperatures that are in between the extremes of the low and high altitudes, thus they are milder climates.

The ID50 for cutaneous anthrax due to Bacillus anthracis is 10 to 50 endospores, while the ID50 for inhalation anthrax is 10,000
Masteriza [31]
<h3>Anthrax is an uncommon, but deadly, disease produced by Bacillus anthracis, a spore-forming bacterium.</h3>

<u>Explanation</u>

  • Anthrax bacteria usually enter the body through a skin wound. You can have become infected if you intake tainted meat or inhale the spores.
  • ID50, the number of microorganisms needed to create a demonstrable infection by 50 percent.
  • The ID50 for cutaneous anthrax attributable to Bacillus anthracis is 10-50 endospores, while the ID50 for inhalation anthrax is 10,000 to 20,000 endospores.
  • Ciprofloxacin is the alternative treatment for anthrax when mutated forms are identified. It is suggested for post- inhalation anthrax.

Consider aerobic cellular metabolism from the beginning to end. What is the sequential order of the metabolic processes that sta
poizon [28]

Explanation:

This starts with substrate level phosphorylation(glycolysis) in the  cytosol of cytoplasms.Two ATPs are needed for phosphorylation of glucose.With eventual formation of  4 ATPs with 2NET GAIN ATPs,NADH+,and Pyruvate.

The Pyruvate reacts with co-enzyme A to form Acetyl coA-This is the bridge reaction or link reaction.

The Acetyl Co-A diffuses into the mitochondria where it combines with oxaloacetate to form citrate,the latter form Alpha ketoglutaric succinic,fumate,malate and back to oxaloacetate.The cycle of events is called the Kreb's Cycle.

Net of 2ATPs are formed,co-enzymes NADH+ and FADH2 ,water molecules,and Co2  are produced.These takes place in the mitochondria.

Then the NADH+ and FADH2 takes the hydrogen ions into the inner mitochondria where Hydrogen is split into electron and Protons.This forms the beginning of oxidative phosphorylation.

The electrons are transmitted by the carrier proteins to form the electron transport chains,which provide the PMF. The latter pumps the protons across  the walls of mitochondria into the intramembrane space.

The high concentration of the protons produce the elecrochemical gradients which make the protons to diffuse back into the matrix. it is the changes in the elctrochemical gradients that supply the energy  needed by ATPase enzymes for synthesis of ATPs. A total of 28ATPs are produced in oxidative phosphorylation.

Answer:

The total ATPs produced in the sequence of glycolysis pyruvatre,Co-enzyme A, kreb's Cycle and oxidative phosphorylation are  32ATPs per molecule of glucose splits in Glycolysis.
