Answer:
It speeds up the reaction rate
Explanation:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
I don’t really have an answer but I have an explanation
Explanation: In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. These pairs of genes then determine certain physical features or traits.
Answer:
152.88 solar unit.
Explanation:
The haploid genome content of the human cell is 3.3 x 10⁹ bp but the human cell is diploid.
So, the content of the diploid cell = 2 ×3.3 x 10⁹= 6.6×10⁹ bp/cell.
1 cell contains DNA = 6.6×10⁹ bp/cell.
10¹³ cell DNA content = 10¹³ x 6.6×10⁹ = 6.6 x 10²² or 6.6 x 10¹⁹ kilo base pairs.
1 kilobase pair of DNA = 340nm = 340 × 10⁻⁹m.
6.6 x 10¹⁹ kilo base pairs of DNA = 340 × 10⁻⁹ × 6.6 x 10¹⁹ = 2244 x 10¹⁰m.
1 meter= 6.2 ×10⁻⁴ miles.
2244 x 10¹⁰m = 6.2 ×10⁻⁴ × 2244 x 10¹⁰m = 13912.8 ×10⁶ miles.
1 solar unit = 9.1 x 10⁷miles.
Then 13912.8 ×10⁶ miles = 13912.8 ×10⁶ miles/ 9.1 x 10⁷miles = 152.88 solar unit.
Total human DNA in terms of solar unit = 152.88 solar unit
Thus, the answer is 152.88 solar unit.
