Answer:
The answer is c)oxygen is an input to acetyl CoA formation.
Explanation:
After pyruvate is produced during glycolysis, its fate depends on oxygen availability. If there is enough oxygen available then pyruvate will enter the citric acid cycle, also called Krebs cycle. Pyruvate will then be oxidized by the pyruvate dehydrogenase complex into acetyl-coA and CO2. However, if there is not enough oxygen available, then pyruvate will undergo a reduction reaction by the lactate dehydrogenase enzyme and produced lactate along NAD+ production from NADH.
Answer:
A visit to the Galapagos Islands in 1835 helped Darwin formulate his ideas on natural selection. He found several species of finch adapted to different environmental niches. The finches also differed in beak shape, food source, and how food was captured.

The objective of this work was to create a pharmacokinetic-pharmacodynamic model to quantitatively predict the distribution of tamoxifen and endoxifen as well as to identify the anti-tumor effect patterns of these drugs.
<h3>What is Tumor growth ?</h3>
A mass of tissue that develops abnormally when cells do not die on schedule or expand and divide more often than they should. Cancer-free tumours might be benign or malignant (cancer). Although benign tumours can become enormous, they do not penetrate or spread to surrounding tissues or to other areas of the body.
- But as a tumour expands, more blood is required to supply the cancer cells with oxygen and other nutrients. Thus, a tumour receives instructions from cancer cells to grow new blood vessels. It is known as angiogenesis.
