Answer:
The correct answer is - option D. fermentation.
Explanation:
Glycolysis is the metabolic pathway in which metabolize the sugar and produce pyruvate molecule or lactic acid and produce the energy in the form of ATP and NADH.
Glycolysis is an example of the fermentation as fermentation is also a metabolic pathway in which an organism turns glucose into the lactic acid or the alcohol to produce energy for electron transfer system.
Thus, the correct answer is - option D. fermentation.
We are tasked to find the substance that is made from
glucose through glycolysis, and supplies energy to living cells through the Krebs cycle when oxygen is present (aerobic respiration), and alternatively
ferments to produce lactate when oxygen is lacking (fermentation). Upon
checking on the Glycolysis cycle, Kreb’s Cycle and fermentation, one common substance
is present and called Pyruvate.
Answer:
The spindle, shown in figure below, consists of fibers made of microtubules. the spindle starts to form during prophase of mitosis kinetochores on the spindle attach to the centromeres of sister chromatids.
Explanation: Chromosomes line up at the metaphase plate under tension from the mitotic spindle.
It’s C. The start point of the cycle. I took this on my test
