The Krebs cycle or the TCA cycle produces
2
C
O
2
for every
1 molecule of acetyl CoA
.
This occurs in Step 3 and Step 4 of the Krebs cycle.
In Step 3,
isocitrate
is oxidized to become
alpha-ketoglutarate
by the rate-limiting enzyme,
isocitrate dehydrogenase
.
In Step 4,
alpha-ketoglutarate
undergoes a redox reaction, oxidizing to become
succinyl-CoA
, also releasing
C
O
2
in the process.
Each step generates the coenzyme,
NADH
, an electron carrier which is going to be important in the next stage of cellular respiration, the electron transport chain.

Leokris [45]

Answer:

Part A: Thr-Leu-Val

Part B: ACC-UUG-GUU

Explanation:

When you transcribe a DNA sequence to mRNA, you need to remember that in RNA there is no Thymine (T), instead it has Uracil (U). So the base pairings would be like this compared to DNA base pairing:

DNA                RNA

A-T                  A-U

T-A                  T-A

C-G                 G-C

G-C                 C-G

Given the sequence the transcription will be as follows:

DNA :   TGG - AAC - CAA  

mRNA: ACC - UUG - GUU

Next, to translate it into amino acids, you will use the chart. Now amino acids pair in codons (3 base pairs at a time).  Let's take the first codon in your sequence:

ACC

1st  2nd   3rd

 A     C       C

Using the column on the left, find the row that matches it, so in this case A.

At the very top, there is another row of letters, looking at the row of A only, look for the column of the second base which is C.

Lastly, look at the right most column and find the letter that matches the third base within the box where A and C intersect. In this case, C is your third base.

The amino acid where all three intersect is your first amino acid which is Thr.

Just do this for the next codons and you will come up with the answer.
