What happens to glucose inside a cell during cellular respiration
Tju [1.3M]
Glucose turns into ATP or ENERGY during the process of cellular respiration ..
<span>The glucose is broken down into 2 molecules of pyruvate, which are two smaller molecules. A net yeild of 2 ATP and 2 NADH result. Each pyruvate is connected to a coenzyme. The resulting molecule is called Acetyl CoA. That reaction also gives off 2 molecules of C02. The Acetyl CoA enters the Krebs Cycle, from which (through a series of steps), 2 more ATP, 6 NADH, 2 FADH2, and 6 CO2 are formed. The 6 NADH and FADH2 (which are coenzymes) move on to the electron transfer chain. Here, they give up their H+ and electrons to the chain. The electrons reduced the proteins on the chain, allowing H+ from outside the cell to be brought in. Bringing this H+ into the cell builds up the concentration. When the concentration gets high enough, the H+ wants to go back out of the cell. The only way to do this is through the ATP synthase. When is passes through this, the synthase combines an ADP with an inorganic phosphate, forming ATP. The typical yeild is 32 ATP from this, giving a total of 36 when you add in the ATP from glycolysis and the Krebs cycle.</span>

Human blood types are characterized by the presence absence of surface markers known as a tigers on the surface of red blood cel
zalisa [80]

Answer:

characterized by presence or absence of antigens

the blood types are A, B, O, AB

Explanation:

There are two antigens and two antibodies that are mostly responsible for the ABO types.  The specific combination of these four components determines an individual's type in most cases. Erythrocytes and serum were related to the presence of antigens on these erythrocytes and antibodies in the serum. these antigens  are A and B, and depending upon which antigen the erythrocytes express, blood either belonged to blood group A or blood group B. A third blood group contained erythrocytes that reacted as if they lacked the properties of A and B, and this group was later called "O" blood group. The fourth blood group AB, was added to the ABO blood group system. These erythrocytes expressed both A and B antigens.

Blood group   Antigen present on RBC    Antibodies in serum    Genotype(s)

      A                        antigen A                             anti-B                     AA or AO

      B                        antigen B                             anti-A                     BB or BO

      AB              both A and B antigen                 none                         AB

      O                           none                           anti-A and anti-B           OO

Which of the following structures is NOT found in some prokaryotic cells?
WARRIOR [948]

The answer would be:

Cilium

<u>Here is more about the structures of prokaryotic cells:</u>

Axial filament is a bundle of flagella that are wrapped around the cell's body.

Flagellum is what the prokaryotic cell has that is whip-like in structure. It helps with the motility of the cell.

Pilus is a hair-like structure that are found on the surface of prokaryotic cells. They help the cell attach itself to surfaces.

Peritrichous flagella are several flagella that can be found all over some prokaryotic cells.
