Which of the diagrams above accurately represents the use of gases in both cellular respiration and photosynthesis?

In the ABO series, the gene for blood type O is , while A and B are genes, and AB is .

Nesterboy [21]

Answer:

Gene for blood type O is recessive

Gene for blood type A and B is dominant

Gene for blood type AB is neither dominant nor recessive but a form of co-dominance

Explanation:

In the ABO blood group,

A and B are dominant genes, O is recessive genes.

So the different genotype and its corresponding phenotype is as follows –

Genotype Phenotype

AO A

BO B

AB AB

AA A

BB B

OO O

Hence, the two alleles AB occur and express together. Therefore, AB blood group is an example of co-dominance.

Blood type also varies with the presence of Rh factor. If Rh factor is present, the blood type will represented with a “+” symbol. And if Rh factor is absent, the blood type will be represented by “-“symbol.

Proteins that speed up (catalyze) chemical reactions are called enzymes. Many enzymes are required for proper metabolic reaction

Scorpion4ik [409]

Answer:

Cobalt Co

Explanation:

Co and Zn can fully replace each other, except perhaps for small individual requirements that are met by minute metal concentrations supplied as contaminants.

In the Cori cycle, when glucose is degraded by glycolysis to lactate in muscle, the lactate is excreted into the blood and retur

Kay [80]

Answer:

Explanation:

Glycolysis is the breakdown of glucose while gluconeogenesis is the formation of glucose. Both pathways are almost the same except that the non-reversible reactions in glycolysis requires another enzyme during gluconeogenesis.

Glycolysis is a 10-step multi-enzyme pathway, in which three of these 10 steps are non-reversible. It is these three steps that basically differentiates the glycolytic pathway from gluconeogenesis. These three steps are bypassed by different enzymes during gluconeogenesis

1. The correct option here is c

Glyceraldehyde 3-phosphate dehydrogenase converts glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate in glycolysis. This reaction is however a reversible reaction, hence this enzyme also converts 1,3-bisphosphoglycerate to glyceraldehyde 3-phosphate during gluconeogenesis.

2. The correct option here is b

Glucose 6-phosphatase converts glucose 6-phosphate to glucose during gluconeogenesis

3. The correct option here is d

Alcohol dehydrogenase converts ethanol into acetaldehyde. This reaction is not present in both glycolysis and gluconeogenesis and hence the enzyme is not involved/present in these pathways.

4. The correct option here is b

Phosphoenol pyruvate carboxykinase converts oxaloacetate to phosphoenol pyruvate during gluconeogenesis

5. The correct option here is a

Phosphofructokinase-1 converts fructose 6-phosphate to fructose 1,6-bisphosphate during glycolysis

6. The correct here is c

Phosphoglycerate mutase converts 3-phosphoglycerate to 2-phosphoglycerate during glycolysis. This reaction is however a reversible reaction and hence this same enzyme converts 2-phosphoglycerate to 3-phosphoglycerate during gluconeogenesis.

7. The correct option here is a

Hexokinase converts glucose to glucose 6-phosphate during glycolysis.

8. The correct option here is d

Pyruvate dehydrogenase converts pyruvate to acetyl-coA. This reaction is one of the fates of pyruvate. This reaction is however not present in both glycolysis and gluconeogenesis and hence the enzyme is not involved/present in both also.

Which diuretic remains effective when creatinine clearance drops below 25 ml/min?

OLga [1]

Loop Diuretics

These are diuretics that exerts effect on the loop of Henle. They are primarily used in heart failure, hypertension and edema. In contrast with Thiazides, loop diuretics are more effective in patients with abnormal kidney function. Loop diuretics inhibit the magnesium and calcium reabsorption in the thick ascending limb of Henle. Loop diuretics is highly protein bound. It has volume of distribution that is limited. This causes the diuretics to be secreted in the convuluted tubules to exert its function.
