Answer:
Oxygen and pyruvate.
Explanation:
The krebs cycle is a stage of cellular respiration and occurs in aerobic organisms. In this case, we can say that the Krebs Cycle only occurs in the presence of oxygen, being essential for the completion of cell respiration.
The Krebs cycle only occurs after the completion of glycolysis, as it needs to be initiated by pyruvate, which is a molecule resulting from glycolysis. In this case, in addition to oxygen, the presence of pyruvate is essential for the krebs cycle to occur.
A good passing current is a small wave for example.
Answer:
Eukaryotic ATP production usually takes place in the mitochondria of the cell.
Explanation:
This ATP production by the mitochondria is done by the process of respiration, which in essence is the use of oxygen in a process which generates energy. Most of the ATP of a eukaryotic organism is made in the mitochondria during the last phase of cellular respiration that is called the electron transport chain (ETC). A mitochondrion is an organelle within a eukaryotic cell.
Answer:
Chloroplast
Explanation:
Chloroplasts are the site of photosynthesis, where in the prescence of light glucose is formed from carbon dioxide and water.
Answer:C
Explanation:It does not support the idea that there is a great reduction in any sector of greenhouse gasses . The lines in the second graph remain reasonably flat throughout the sectors in the graph.
