Why do proteins have to have a 3d shape in order to function properly?

2 answers:

7 0

Protein is made up of a sequence of amino acids. The shape of the protein is usually characterize by the sequence of amino acids present. The functionality of protein is based on its shape. The shape of the protein can be a primary, secondary and tertiary. Tertiary structure of the protein allows it to interact or bind with other molecule in a specific way to perform a specific task.

Answer:

Proteins are the biomolecule present inside the the living organisms. Proteins are made of the polymers of the amino acids that are linked together by peptide bond.

Proteins are biologically active in its 3D conformation and shape. The 3D shape of the protein is achieved by the proper sequence of the amino acids and its folding. Any change in 3D structure of the protein will result in the loss of biological activity of the protein because of the alteration in the amino acid sequence. The 3D shape of proteins is important as it helps the enzymes to work properly to carry out chemical reactions of the body.

Initial inputs of energy, water, fertilizer, and pesticides on high-yield crop varieties may initially have dramatic results. At

Tanya [424]

Answer:

Principle of diminishing returns

Explanation:

In this case, Initial inputs of energy, water, fertilizer, and pesticides on high-yield crop varieties would produced high crop yields. As time goes on further adidtion of these same inputs of production would give the same or a lower yields of crops. Therefore, obeying the Principle of diminishing returns.

What of the following correctly identifies some of the molecules produced from the glucose synthesised by photosynthesis?

Yuliya22 [10]

Answer:

plant life use a system known as photosynthesis to make meals.

at some stage in photosynthesis, plant life entice mild strength with their leaves.

plant life use the strength of the solar to extrade water and carbon dioxide right into a sugar known as glucose.

glucose is utilized by plant life for strength and make different materials like cellulose and starch.

cellulose is utilized in constructing mobileular walls. starch is saved in seeds and different plant components as a meals source.

I need help with this (#20)

tester [92]

Answer:

a Anaphase I

b Metaphase I

c Telophase I

d Anaphase II

e Prophase I

f Telophase II

Explanation:

Prophase I begins after the DNA has been duplicated, as shown in picture e. The chromosomes are condensed, and also visible, which is apparent in picture e.

The next stage is called Metaphase I, in which the pairs of homologous chromosomes align at The the centre of the cell and the spindle fibres attach, as shown in picture b.

The pairs of chromosomes are pulled apart to opposite poles of the cell by the spindle fibres., as shown in picture a. This stage is called Anaphase I.

Then, a process called Telophase I occurs, when the cell divides into two daughter cells. One of these cells is shown in picture c.

Picture d shows the stage Anaphase II, where the spindle has attached and the chromatids are pulled to the opposite poles of the cell.

The final picture left is picture f, which shows the daughter cell at the end of meiosis II, where the nuclear envelope is reforming, as in telophase II.

A trihybrid cross is a cross between two individuals who are heterozygous for three genes. For example: AaBbCc x AaBbCc. Assumin

Mariulka [41]

Answer:

27:9:9:9:3:3:3:1

Explanation:

The gametes of the parental genotypes would be

ABC, ABc, AbC, aBC, Abc, aBc, abC, abc

The cross between AaBbCc and AaBbCc will result into following offspring (image is also attached)

ABC ABc AbC aBC Abc aBc abC abc

ABC AABBCC AABBCc AABbCC AaBBCC AABbCc AaBBCc AaBbCC AaBbCc

ABc AABBCc AABBcc AABbCc AaBBCc AaBbcc AaBBcc AaBbCc AaBbcc

AbC AABbCC AABbCc AAbbCC AaBbCC AAbbCc AaBbCc AabbCC AabbCc

aBC AaBBCC AaBBCc AaBbCC aaBBCC AaBbCc aaBBCc aaBbCC aaBbCc

Abc AABbCc AABbcc AAbbCc AaBbCc AAbbcc AaBbcc AabbCc Aabbcc

aBc AaBBCc AaBBcc AaBbCc aaBBCc AaBbcc aaBBcc aaBbCc aaBbcc

abC AaBbCC AaBbCc AabbCC aaBbCC AabbCc aaBbCc aabbCC aabbCc

abc AaBbCc AaBbcc AabbCc aaBbCc Aabbcc aaBbcc aabbCc aabbcc

The genotype ratio is 27:9:9:9:3:3:3:1

What does the operon model attempt to explain?

sergiy2304 [10]

Answer:

a. the coordinated control of gene expression in bacteria

Explanation:

An operon in bacteria is a collection/cluster of genes that are under the control of a single promoter. It includes 3 components: a promoter, the genes and an operator. The operator is where a repressor binds, and the promoter is where transcription begins.

Operons allow organisms to control the expression of multiple genes in response to environmental cues
