How many molecules of carbon dioxide (CO2) would be produced by five turns of the citric acid cycle?

Biology
1 answer:
ser-zykov [4K]3 years ago
8 0

Answer:

The correct answer is E) 10

Explanation:

Glucose is partially oxidized during the glycolysis process into two pyruvate molecules. Then these pyruvate molecules get totally oxidized into CO2 during the citric acid cycle. This citric acid cycle occurs in the matrix of mitochondria.

During a single turn of the citric acid cycle, 2 molecules of carbon dioxide are released. Apart from two molecules of CO2, 3 molecules of NADH, 1 molecule of FADH2 and 1 molecule of ATP or GTP are also produced.

So if 2 molecules of CO2 are produced in one turn therefore in 5 turn 10 molecules of CO2 will be produced.

NEED HELP ASSAAPP!!!! 2. What protein changes shape in sickle cell anemia? What are two effects of this change?
mixer [17]

Answer:

Hemoglobin

Explanation:

Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. With SCD, the hemoglobin forms into stiff rods within the red blood cells. This changes the shape of the red blood cells. The cells are supposed to be disc-shaped, but this changes them into a crescent, or sickle, shape.

The sickle-shaped cells are not flexible and cannot change shape easily. Many of them burst apart as they move through your blood vessels. The sickle cells usually only last 10 to 20 days, instead of the normal 90 to 120 days. Your body may have trouble making enough new cells to replace the ones that you lost. Because of this, you may not have enough red blood cells. This is a condition called anemia, and it can make you feel tired.

The sickle-shaped cells can also stick to vessel walls, causing a blockage that slows or stops the flow of blood. When this happens, oxygen can't reach nearby tissues. The lack of oxygen can cause attacks of sudden, severe pain, called pain crises. These attacks can occur without warning. If you get one, you might need to go to the hospital for treatment.

Why the numerical values on the X and Y axis has to be consistent?
natulia [17]

Answer:

Each axis needs a scale to show the range of the data on that axis. The low end of the scale may be zero or a round number value slightly smaller than the smallest data point. The high end of the scale is usually a round number value slightly larger than the largest data point. The scale is measured off in major and minor tick marks. Typically the scale runs from low to high in easily counted multiples like 10s, 50s, 100s, etc. When graphs are compared side-by-side, consider scaling them to the same data range to make comparisons easier.

Why is it so important to properly don and remove personal protective equipment?
artcher [175]
<span>Personal protective equipment is only helpful if regulations for using it are followed carefully. If it is not worn and used properly, then it will not function properly and it might not provide the protection that is needed in the situation. For example, a helmet is only effective if it is fitted properly and snugly on the head. Otherwise it could fall off in an accident and be rendered useless.</span>
