Answer:

a .carbon dioxide(Co2) and water (H2O)

b. air and soil

Explanation:

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Help please!........................................................
bogdanovich [222]

Answer:

The correct order would be

  • Glucose
  • ATP→ADP
  • H₂O
  • Pyruvate
  • CO₂

Explanation:

Following reactions occur in Glycolysis and Kreb's Cycle

  1. Phosphorylation of Glucose- In the first step of glycolysis, Glucose is converted into Glucose-6-Phosphate using 1 ATP molecule by Hexokinase enzyme. One phosphate group from ATP is attached to glucose by the enzyme, thus forming ADP.
  2. Dehydration- In the ninth step of Glycolysis, each of two molecules of  2-Phosphoglycerate are converted to Phosphoenol Pyruvate, by Enolase enzyme, releasing two H₂O molecules.
  3. Formation of Pyruvate- In the last or tenth step of Glycolysis, each of two molecules of Phosphoenol Pyruvate are converted to Pyrutave using an ATP by the enzyme Pyruvate Kinase.
  4. Oxidation Of Pyruvate to Acetyl-CoA- Before the Kreb's Cycle starts, the Pyruvate molecule obtained from the Glycolysis undergoes oxidative decarboxylation producing Acetyl-CoA and release of CO₂ and NADH.

The distance from one molecule in a body to the nearest molecule in the body occupying a similar position and moving in the same
creativ13 [48]
The answer is wavelength. It is the distance between corresponding points of two consecutive waves (corresponding points are particles or points in the same phase, meaning the points have completed identical fractions of their periodic motion. In a transverse wave it is the distance between two successful crests or troughs while in a longitudinal wave is the distance between two successful compressions or rarefactions.
