Photosynthesis

Explanation:

One of the metabolic pathways from the given options is photosynthesis. During catabolism, there is a build up of materials from smaller ones.

Metabolism is a process that either involves the building up of materials or the breaking down to release energy.
The building up of matter or energy is anabolism.
The breaking down is known as catabolism.
During the process of photosynthesis, green plants manufacture their food from carbon dioxide and water in the presence of sunlight.
The products are glucose and oxygen gas.
Energy is stored in the glucose as a chemical form of energy.
This is an anabolic process.
Respiration, breakdown of actin in muscles and alcohol fermentation are catabolic processes.

In the above diagram of a plant cell, what is the function of structure 3?

kramer

Explanation:

B. serves as the control center of the cell and contains the cell's genetic information

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wounucleuscarbohynd around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

Further Explanation:

A cell's structural components (i.e. their makeup) determine their function (what they do) . For instance, photosynthesizing cells in algae and plants have structures called chloroplasts. These contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates. In specific cell types, collected proteins may function as a unit called an organelle. Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they:

may increase metabolic reaction efficiency; they allow cells to concentrates smaller fractions of enzymes and solutes
separate proteins and molecules that me harm the cell by parceling them into membrane-bound organelles for example, proteaseas bound within lysosomes can break down many structural proteins

Which class of enzymes catalyzes reactions involving the formation of double bonds?

vodka [1.7K]

Lyases

Lyases are class of enzymes that catalyzes reactions involving the formation of double bonds.

Lyases are class of enzymes that catalyzes the joining of C-C ( carbon to carbon), C-O (carbon to oxygen), and C-N (carbon to nitrogen) bonds by hydrolysis or oxidation. These bonds are usually held by the process of elimination which leads to the formation of new double bonds or cyclical molecules. Examples of lyases include; aldolase and adenylate cyclase.

Which process is the first step of making a protein from DNA instructions?

-BARSIC- [3]

The first step of protein synthesis is called transcription. The DNA transcription to mRNA is actually the first step of the protein synthesis. During the transcription step the instructions encoded in the DNA of the genes are transcribed into the nucleotide sequence code of a ribonucleic acid (RNA)....

Dr. Paul Ehrlich observed that the differential stain developed by Dr. Gram suggested bacteria could be killed differentially by

Alex787 [66]

Answer:

The correct answer is Glycocalyx, ribosome and cell wall.

Explanation:

Glycocalyx is mainly found in bacteria that makes a protective covering outside the cell wall in the form of capsule of bacteria and provide protection to bacteria from host immune cell.

Bacterial ribosomes are different from human ribosomes. Bacteria contain 70s ribosome while humans contain 80s ribosome so ribosomes are potential targets for many drugs present today.

Bacterial cell contain cell wall which is made up of peptidoglycan or lipopolysaccharide but human cell does not contain a cell wall, therefore, many drugs are designed to destroy cell wall of bacteria like penicillin.

So glycocalyx, ribosomes, and cell wall can be potential targets for Dr. Ehrlich's "magic bullets" due to significant difference or absence from humans.
