Sarah is writing a paper explaining protein formation. Choose the correct way to complete each sentence.

Chemistry
1 answer:
Amanda [17]3 years ago
8 0

Answer :

Amino acids join by forming (1) peptide bonds.  Water is released.

The chains of amino acids vary according to their (2) side chains, which each have differing makeup.  

These chains determine the protein’s structure and they fold to create a unique (3) third-dimensional shape.

Explanation :

Amino acid : The amino acids are the building blocks of protein. Amino acids are the compound which consist both amine (-NH_2) and carboxylic (-COOH) groups along with the side chains. In the protein, many amino acids are linked by the peptide bonds.

Th peptide bonds are formed by the combining of amino group of one amino acid to the carboxylic group of another amino acid by releasing of water.

Some examples of amino acids are glycine, lysine, alanine, etc.

Peptide bond formation image is shown below.

In the image 'R' can be contained by different groups like hydrogen, methyl, phenyl, etc

A 6.165 gram sample of an organic compound containing C, H and O is analyzed by combustion analysis and 10.27 grams of CO2 and 3
e-lub [12.9K]

Answer:

Explanation:

mass of carbon in 10.27 g of CO₂ = 12 x 10.27 / 44 = 2.80 g

mass of hydrogen ( H ) in 3.363 g of H₂O = 2  x 3.363 / 18

= .373 g

These masses would have come from the sample of 6.165 g .

Rest of 6.165 g of sample is oxygen .

So oxygen in the sample = 6.165 - ( 2.8 + .373 ) = 2.992 g

Ratio of C  , H , O in the sample

2.8 : .373 : 2.992

C: H : O : : 2.8 : .373 : 2.992

Ratio of moles

C: H : O : : 2.8/12 : .373/1 : 2.992 / 16

C: H : O : : .2333 : .373 : .187

C: H : O : : .2333/.187 : .373/.187 : .187/.187

C: H : O : : 1.247 : 1.99 : 1

C: H : O : : 5 : 8 : 4 ( after multiplying by 4 )

Hence empirical formula

C₅H₈O₄

Molecular formula ( C₅H₈O₄ )n

n ( 5 x 12 + 8 x 1 + 4 x 16 ) = 132

n x ( 60 + 8 + 64 ) = 132

n = 1

Molecular formula = C₅H₈O₄.

Which of the following is not equal to 0.1 centimeters?
Anon25 [30]

Answer:

c) 10 millimeters (mm)

Explanation:

The unit conversions are as follows:

1 cm = 10 mm (millimeter)

1 cm = 0.01 m (meter)

1 cm = 0.00001 km (kilometer)

1 cm = 10000 μm (micrometer)

Based on the above conversions:

0.1 cm = \frac{10 mm*0.1 cm}{1 cm} = 0.1 mm

0.1 cm = \frac{0.01 m*0.1 cm}{1 cm} = 0.001 m

0.1 cm = \frac{0.00001 km * 0.1 cm}{1 cm} = 0.000001 km

0.1 cm = \frac{10000 um*0.1cm}{1 cm} =1000 um

Therefore, 0.1 cm = 10 mm is incorrect instead it is 0.1 mm

Helga [31]

Answer: Membrane Protiens

Explanation:

In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it.
