<h2><u>Full Question:</u></h2>
Which statement correctly compares and contrasts the three stages of cellular respiration that occur in the presence of oxygen? Each stage occurs in the mitochondria, but only the final stage produces ATP. Each stage produces ATP, but only the third stage occurs in the mitochondria. Each stage produces ATP, but only the first stage occurs in the cytoplasm. Each stage occurs in the cytoplasm, but only the final stage produces ATP.
<h2><u>
Answer</u>:</h2>
Each stage produces ATP, but only the first stage occurs in the cytoplasm.
<h3><u>Explanation</u>:</h3>
Cellular respiration is the process by which the glucose or any respiratory substrate is burned down inside a cell producing ATP or energy. This process of cellular respiration is seen in each and every living cell. The glucose is burned in the cytoplasm of the cell producing the pyruvate. This pyruvate is decarboxylated into Acetyl CoA and transferred inside the mitochondria. So the glycolysis or the 1st step of cellular respiration occurs in cytoplasm and rest inside the mitochondria.
ATP is produced from each astep of cellular respiration. So the correct option is option C.
Answer:
Animals - Plants - Energy
Plants gain energy through photosynthesis, which is then eaten by animals, which gets eaten by animals, etc.
Then, Animals die, and the energy is passed on to the soil, which passes to the plant.
Statement 3 is the best choice
Answer:
Organelle
Explanation:
The general name given to membrane bound structures eukaryotic cell that perform specific function for necessary cell survival.
Answer:
Bicarbonate ion, HCO3- (which has a similar charge to chloride ions) also follow sodium ions into the blood. Also, potassium ions, K+ are transported into the nephron so some chloride ions and bicarbonate ions remains in the nephron to balance the charge.
Explanation:
Sodium is the primary positively charged electrolyte in extracellular fluid. Most of the solute reabsorbed in the proximal tubule is in the form of sodium bicarbonate and sodium chloride. Water is also reabsorbed in order to balance osmotic pressure
When sodium ions are reabsorbed into the blood, few of the substances that are transported with Na+ on the membrane facing the lumen of the tubules include Cl- ions, Ca2+ ions, amino acids, and glucose. Sodium is actively exchanged for K+ using ATP on the basal membrane.
In the distal convoluted tubule, K+ and H+ ions are selectively secreted into the filtrate, while Na+, Cl-, and HCO3- ions are reabsorbed to maintain pH and electrolyte balance in the blood.
Some chloride ions remains in the nephron to balance the charge of the secreted K+ ions and also due to the bicarbonate ions that are removed.
