Answer: They consist of long chains of C, H, and O.

Explanation:

In terms of chemical composition, lipids differ from nucleic acids and proteins because they mostly just contain carbon, hydrogen, and oxygen (except for phospholipids which of course contain phosphorous). In addition to those elements, proteins contain nitrogen and sulfur, and nucleic acids contain nitrogen and phosphorous.

Carbohydrates share the C, H, and O composition as lipids, but they differ in structure. Lipids are generally exist as triglycerides, which consist of a triple hydroxyl alcohol (glycerol) that has bonded to three long-chain carboxylic acids (fatty acids) in a triple condensation reaction. Carbohydrates on the other hand are made of carbon ring structures that either remain alone or polymerize into long polysaccharide chains.

N the early 1900's a scientist hypothesized a link between DNA and the production of proteins in the cytoplasm. However, the fac

DanielleElmas [232]

The newly identified molecule was RNA.

The cytoplasm synthesize protein through the ribosomes.

The molecule that transports information from the nucleus to the cytoplasm is the tRNA or the transfer RNA.

Thymine is a DNA base which is one of the building blocks in making protein.

Match the function with the cell part. Part A1. You will use each term only once. 2. Contains DNA and directs synthesis of RNA 3

EleoNora [17]

Answer:

1. Contains DNA and directs synthesis of RNA B. Nucleus 

2. Photosynthesis - make energy H. Chloroplast

3. Protein synthesis and folding D. Rough ER 

4. ATP production, cellular respiration A. Mitochondria 

5. Transport molecules around cell C. Vesicle 

6. Functions in storage and digestion F. Vacuole

7. Lipid and carbohydrate synthesis  E. Smooth ER 

8. Modifies, sorts, tags, packages, distributes proteins G. Golgi Apparatus

Explanation:

The cell is the functional unit of all living organism, it´s enclosed by a MEMBRANE in animals, or by a CELL WALL in plants and it´s formed by several organelles that are dispersed in the intracellular fluid or CYTOPLASM, positioned along the CYTOSKELETON, which gives structural integrity to the cell. Vacuoles, Chloroplast and Cell wall are found in plant cells. Each organelle has a distinct function within the cell:

Nucleus - Contains DNA and directs the synthesis of RNA.

Chloroplast - Photosynthesis - make energy.

Rough ER - Protein synthesis and folding.

Mitochondria - ATP production, cellular respiration.

Vesicle - Transport molecules around cell.

Vacuole - Functions in storage and digestion.

Smooth ER - Lipid and carbohydrate synthesis.

Golgi Apparatus - Modifies, sorts, tags, packages, distributes proteins.
