<span>Which of the following statements is true about cellular respiration?
</span>1. I believe the answer is It breaks down food to release energy.
<span>
Cellular respiration is a chemical reaction that turns food into energy. The food that mostly used by the organism is carbohydrate. The breakdown of carbohydrate needs oxygen to maximize energy produced. </span>Cellular respiration<span> will create carbon dioxide and water as the side product. Photosynthesis and respiration happen in the living organism.
</span><span>2. The answer is Diffusion
The question is asking the movement of carbon molecule between seawater(liquid) and air(gas). Gas like carbon dioxide or oxygen can move from the water into the air by diffusion. This allows the seawater organism to utilize oxygen and carbon that vital for its life. </span>
Each round of Citric Acid Cycle produce 2 molecules of carbon dioxide. So one cycle of TCA cycle is enough to convert Acetyl CoA to carbon dioxide.
<h3><u>Explanation: </u></h3>
Citric Acid Cycle or Kreb's Cycle or the TCA cycle is the 1st dedicated step towards the aerobic respiration. The end product of glycolysis is Pyruvate which is a three carbon compound. It's acted upon by Pyruvate Decarboxylase to produce a 2 carbon compound Acetyl CoA and a molecule of carbon dioxide. This Acetyl CoA now reacts with oxaloacetate to produce Citric Acid which is the 1st step of Citric Acid Cycle. This now produce several intermediates and a lot of reduced electron carriers along with 2 molecules of carbon dioxide and ends up being oxaloacetate again. So one cycle of Citric Acid Cycle is necessary to convert Acetyl CoA to CO2.
Answer: Density is a measure
Explanation: The more squashed together an object’s particles are, the denser it is.
Answer:
2.13 × 10²² moles
Explanation:
Relation between Mole and Mass is,
Mole = Mass / M.Mass
Putting values,
Mole = 2.3 × 10²⁴ g / 107.87 g/mol
Mole = 2.13 × 10²² moles
