During cellular respiration, NADH:________.a. is converted to NAD+ by an enzyme called dehydrogenase. b. none of the choices are
skad [1K]

Answer:

a. is converted to NAD+ by an enzyme called dehydrogenase

Explanation:

The electron transport chain of cellular respiration is the final step that oxidized NADH and FADH2. These reducing powers are formed during glycolysis and Kreb's cycle. Complex I of the electron transport chain present in the inner mitochondria membrane is NADH dehydrogenase. This protein complex accepts electrons from NADH and oxidizes it into NAD+. NADH dehydrogenase couples oxidation of NADH with the pumping of proton towards the intermembrane space.

Sav [38]

Answer:

All cells contain genetic information in the form of DNA molecules. ... Empirical evidence is required to differentiate between cause and correlation and to make claims about the role of DNA and chromosomes in coding the instructions for the characteristic traits passed from parents to offspring.

A scientist is trying to find a method to artificially produce a protein that is found in a pig kidney what would be the first s
dedylja [7]

Answer:

The initial step of producing protein in a pig kidney artificially may involve the study of number mRNA produced by kidney.

Explanation:

As the protein is produced mainly in the kidney by studying the mRNA produced in it. It shows the locations of kidney elevated proteins such as the – proximal tubules, glomeruli etc. The maximum amount of proteins is seen in the genes, present in the kidney.

The whole system of kidney shows that the gene expression is shared mostly with the liver.  So while producing the artificial protein in pig kidney, the number of mRNA should be considered.

iogann1982 [59]

A metabolic manner referred to as cellular respiration converts glucose to ATP. Glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation are the stages of cellular respiration.

Four steps of Cellular Respiration

  1. Glycolysis. During glycolysis, the six-carbon sugar glucose is going thru some of chemical changes. In the end, it's miles converted into molecules of pyruvate, an natural molecule with 3 carbons.
  2. Oxidation of pyruvate. The mitochondrial matrix, the inner most compartment of the mitochondria, gets every pyruvate produced for the duration of glycolysis.
  3. Cycle of citric acid. A four-carbon molecule and the created acetyl CoA engage and go through a chain of events, in the end renewing the preliminary four-carbon molecule.
  4. Phosphorylation through oxidation A gradient is created as protons are pumped out of the matrix as electrons flow down the chain, liberating power as they do so. Through the introduction of ATP through the enzyme ATP synthase, protons float returned into the matrix.

Chemical Energy: C6H12O6 6O2 → 6CO2 6H2O (in ATP)

According to the equation, oxygen (O2) and glucose (C6H12O6) react to provide carbon dioxide (CO2) and water (H2O), which releases power. Cellular respiratory is an cardio manner because oxygen is essential for it to occur.
