NNADVOKAT [17]
Well, considering that seagulls, bears, and cows are warm blooded mammals, and spiders are arachnids with an exoskeleton, I'm willing to bet that spiders are ectothermic. And isn't the word exothermic?

What accounts for the variation Darwin observer among island species
vovangra [49]

Answer AND Explanation:

The islands had different environments, and the organisms had adaptations that enabled the organism to live in those environments. The island had been inhabited by its own kind of species found nowhere else in the world. Darwin also noticed that considerable variation exists between members of the same species. Offspring vary from their parents and between themselves.

2a) Which of the following statements about pyruvate oxidation IS TRUE?
Darina [25.2K]

The true statements are:

  • Substrate level phosphorylation ocvurs during Pyruvate oxidation
  • 32 ATP molecules can be made by cellular respiration but only 2 ATP molecules when oxygen is lacking
  • Electrons move from protein to protein due to increasing electronegativity in the electron transport chain
  • ADP is phosphorylated in the matrix of the mitochondria during oxidative phosphorylation
  • ATP inhibits pyruvate dehydrogenase by feedback inhibition

<h3>What is glucose oxidation?</h3>

Glucose oxidation refers to the process in the cells in which glucose molecules are oxidized to form ATP and carbon dioxide in the presence of oxygen.

The first stage of glucose oxidation is the conversion to pyruvate.

Pyruvate is oxidized to acetylCoA.

AcetylCoA enters the citric acid cycle to produce reducing equivalents, NADH for the electron transport chain.

  • The true statements about pyruvate oxidation is that there is substrate level phosphorylation during the process
  • When there is sufficient oxygen, 36 ATP molecules can be made (theoretically) by cellular respiration. However, when oxygen is lacking, only 2 ATP molecules are made.
  • In the electron transport chain of cellular respiration, electrons move from protein to protein due to increasing electronegativity
  • During oxidative phosphorylation, ADP is phosphorylated in the matrix of the mitochondria
  • Aerobic respiration can be regulated by feedback inhibition of pyruvate dehydrogenase by ATP.
