How do temperatures and light intensity influence the rate of photosynthesis

2 answers:

7 0

As light intensity increases, the rate of photosynthesis will increase as long as other factors are in adequate supply. As the rate increases, eventually another factor will come into short supply.

Well the plants use photosynthesis to get their energy and if they dont have sunlight then they cant get very much energy because that is their main energy source.

What organelle does the mRNA strand go to so protein synthesis can start?

sergiy2304 [10]

Answer:

The mRNA strands go to the cytoplasm to meet ribosomes so protein synthesis can start.

Explanation:

In protein synthesis, the first step is to synthesize messenger RNA, mRNA. The coping process of the DNA section for the desired protein is called transcription, and it happens in the nucleus. After that, it occurs translation, when the formed mRNA moves to the cytoplasm through the nucleus membrane pores. Protein synthesis is initiated in the cytoplasm when mRNA meets a free ribosome, the primary structure for protein synthesis. Ribosomes are made of protein and ribosomal RNA and can be found in the rough endoplasmic reticulum or floating in the cytosol. They read the mRNA code and add the correct amino acid using transference RNA to build the protein. mARN has a start and end codon that tells where to start and stop adding amino acids. When the ribosome reaches the end codon, it means that protein synthesis is finished. The new protein is driven to the rough endoplasmic reticulum and translocated to the lumen. Once there, the protein suffers a few modifications, one of them is folding to become functional. Finally, protein is transported by vesicles to the Golgi complex, and from there to its final destiny.

Proteins are important food nutrients. A technician working at a food company is interested in the nutritional content of seeds/

Vladimir79 [104]

Answer: Sample 1 then, has more variety of proteins but less quantity of each one, while sample 2 has less variety but more quantity of the two proteins present.

Explanation:

Proteins are molecules found in the cells of all living organisms. A protein is composed of monomers called amino acids linked together by peptide bonds. To analyze proteins, a technique called SDS-PAGE (sodium dodecyl sulfate polyacrylamide gel electrophoresis) is used. This technique is used to separate proteins according to their electrophoretic mobility, depending on polypeptide chain length, molecular mass, post-translational modifications and other factors. SDS (sodium dodecylsulfate) is an anionic surfactant compound that breaks non-covalent bonds in proteins, denatures them causing these protein molecules to lose their native conformation and provides the polypeptide with a negative charge that is proportional to the chain length (the number of amino acids) and, therefore, to the molecular mass of the protein. The electrostatic repulsion created by the binding of SDS to the protein is one of the causes of the protein losing its native conformation, thus eliminating the differences in conformation of the different proteins to be separated in the gel.

An electric current is applied to the gel where the proteins are seeded, causing the negatively charged proteins to migrate through the gel in the direction of the anode (positively charged region). Short proteins will move more easily and faster through the pores of the gel, while larger proteins will find it more difficult to do so. After a certain time, the proteins will have migrated according to their size (measured in kDa or kiloDaltons). After electrophoresis, the gel should be stained with Coomassie blue or silver stain, allowing visualization of the separated proteins. After staining, the different proteins will appear as distinct bands on the gel. In addition, the higher the amount of a protein, the more intense the color of its band will be.

Extract No. 1 shows three bands: 25, 30 and 35 kDa. This means that it has three different proteins, each with a different molecular weight. Extract number 2 shows two bands: 25 and 35 kDa. It means that this sample has only 2 proteins. And being bands of higher intensity, we can say that there is more of each protein.

Sample 1 then, has more variety of proteins but less quantity of each one, while sample 2 has less variety but more quantity of the two proteins present.

The saturated fats of animals differ from the unsaturated ones of plants. Unsaturated fats have

poizon [28]

Solution;

Unsaturated fats are typically liquid at room temperature. Unsaturated fats come primarily from plant foods, such as nuts and seeds, and. Examples include vegetable oils such as olive, peanut, safflower, sunflower, soybean and corn etc

While,

Saturated fats – which are found in butter, cheese, red meat and other animal-based foods. Decades of sound science has proven it can raise your “bad” cholesterol and put you at higher risk for heart disease.

Thus the saturated fats are differs from the unsaturated fats.
