Biology

Otrada [13]3 years ago
3 0

Answer:

Entner-Doudoroff (ED) pathway is the pathway is a series of chain reaction which converts the glucose molecule to pyruvate unlike in the glycolysis where the glucose is converted to phosphoenolpyruvate.

The enzymes used in the ED pathway are different from the enzymes used in the PPP pathway and glycolysis. The pathways are used by the gram-negative bacteria and archaea and few gram-positive bacteria.

The ED pathway produces only 1 ATP, 1 NADPH and 1 NADH therefore the microbes which use this process are aerobic microbes.

The ED pathway is used by the microbes which lack the enzymes for the glycolysis process like Rhizobium, Azotobacter, Pseudomonas and others. Since this is an alternative method to produce energy molecule which lacks the glycolytic enzymes therefore this is an advantage to certain microbes.

Sunny_sXe [5.5K]

Answer:

probability of the child having attached earlobes since it is recessive i.e (yy)

=1/4

=0.25 × 100%

=25%

Explanation:

If two heterozygous individuals have a child

i.e let the heterozygous individuals be  = Xy

if both traits crosses together; their F₁ offspring will be;  (XX, Xy, Xy, yy)

Xy  ×   Xy

          X             y

X        XX          Xy

y       Xy            yy

probability of the child having attached earlobes since it is recessive i.e (yy)

=1/4

=0.25 × 100%

=25%

Which of the following accurately describes the role of energy in cellular respiration?
zmey [24]

Answer:

The correct answer is option energy is a product.

Explanation:

Cellular respiration is a process in which oxidation of food or glucose takes place to produce energy. This process proceeds in four processes: glycolysis, oxidative carboxylation, Krebs cycle and electron transport chain.

All of this process produces energy in the form of ATP or energy equivalents like NADH and FADH₂.  

1. Glycolysis produces- 2 ATP, 2 NADH,  

2. Oxidative carboxylation produces- 2 NADH,  

3. Krebs cycle produces- 2 ATP, 6 NADH AND 2 FADH₂ and  

4. Electron transport chain produces at last- 24 ATP from these reducing equivalents.

Thus, option energy is a product is a correct option.
