Answer:
The correct answer is D. 1/8
1 out of 8 is the probability of having three girls in a row.
Answer:
a) Total of ATP produced in glycolysis is equal to 2
ATP produced:
i) 1,3‑bisphosphoglycerate → 3‑phosphoglycerate (2 ATP are produced)
ii) phosphoenolpyruvate→pyruvate (2 ATP are produced)
b) 26 pyruvate molecules.
Explanation:
a) Glycolysis consists of two steps in which ATP is consumed and two steps in which ATP is released.
ATP produced = 4
ATP consumed = 2
The total of ATP produced in glycolysis is equal to 2 (4-2)
ATP produced:
i) 1,3‑bisphosphoglycerate → 3‑phosphoglycerate (2 ATP are produced)
ii) phosphoenolpyruvate → pyruvate (2 ATP are produced)
b) In the sixth step of glycolysis, inorganic phosphate molecules are consumed:
glyceraldehyde-3‑phosphate → 1,3‑bisphosphoglycerate
2 pi are added in glycolysis. As each glucose molecule undergoes glycolysis, the pi required by the 13 glocosa molecules is 26 (13 * 2). Glycolysis of each glucose produces 3 pyruvates, so 13 glucose molecules will produce 26 pyruvate molecules.
This process is active transport.
Unlike other methods such as diffusion or osmosis, active transport requires extra energy provided by the organism from such as cellular respiration. In addition, they also require a carrier protein, which can change its shape to bring the substance through the cell membrane.
Some examples requiring active transport may include root hair cells absorbing mineral ions, or our small intestine absorbing digested nutrients into our body.
