Answer:
In translocation, a piece of chromosome or a whole chromosome breaks off during meiosis and attaches itself to another chromosome. The presence of an extra part of the number 21 chromosome causes the features of Down syndrome.
Answer:
Eukaryotes share a common ancestry
Explanation:
molecules that control the stages of the cell cycle in all eukaryotes are similar.
A. the amount of available food.
One molecule of Glucose produces 38 molecules of ATP through the ETC in presence of enough oxygen.
<h3><u>Explanation:</u></h3>
To know the number of ATP produced from a molecule of glucose, we need to know the total amount and the type of products produced in the 3 individual steps of an aerobic respiration.
1. <u>Glycolisis</u> - In glycolisis, one molecule of glucose is converted into two molecules of pyruvate with production of 2 ATP molecules and 2 molecules of NADH.
2. <u>Pyruvate Dehydroogenase step</u> - Two molecules of pyruvate produce a total of 2 NADH.
2. <u>Kreb's Cycle</u> - In Kreb's Cycle, two molecules of Acetyl CoA produce a total of 6 NADH, 2FADH and 2 GTP which is again equivalent to 2 ATP.
In the ETC, each NADH is converted into 3 molecules of ATP and each FADH is converted into 2 molecules of ATP.
In the whole process till now, total of 10 molecules of NADH, 2 molecules of FADH and 4 ATPs.
So total number of ATP produced is 10*3 + 2*2 + 4 = 30+4+4 =38.
