What is the function of the;
MakcuM [25]
Cell membrane: Scattered in the lipid bilayer are cholesterol molecules, which help to keep the membrane fluid consistent. Membrane proteins are important for transporting substances across the cell membrane. They can also function as enzymes or receptors. On the extracellular fluid side of a cell membrane, you find carbohydrates.

Cytoplasm: Function of Cytoplasm. The jelly-like fluid that fills a cell is called cytoplasm. It is made up of mostly water and salt. Cytoplasm is present within the cell membrane of all cell types and contains all organelles and cell parts.

Nucleus: Function of the Nucleus. The nucleus is an organelle found in eukaryotic cells. Inside its fully-enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.

Cell wall: The cell wall is the protective, semi-permeable outer layer of a plant cell. A major function of the cell wall is to give the cell strength and structure, and to filter molecules that pass in and out of the cell.

noname [10]
The correct question for this is: "<span>The concentration of proteins synthesized in the breast are more affected by _____ than _____."

The correct answers are the age of the infant and maternal intake and maternal serum proteins. 

While maternal intake and serum proteins contribute to the proteins synthesized in the breast tissue, the age of the infant will affect the composition of the breast milk as he or she ages. This is because of the reason that the demand for nutrients of the infant should be fulfilled until the recommended breastfeeding age of 2 years old.</span>

List and describe three factors that affect how quickly enzymes can work to catalyze reactions
Lilit [14]

Answer:

The correct answer is - temperature, pH, substrate concentration.

Explanation:

Various factors affect the rate of enzymatic reaction such as pH, temperature, substrate concentration, availability of activators or inhibitors in the reactions, and enzyme concentration.

Temperature: Temperature affects the rate of the enzyme-catalyzed reactions. Like most of the reactions with an increase in temperature rate of enzymatic reaction also rises up to a maximum level and then declines if the temperature continues to increase as enzyme denatures after a particular temperature.

pH: Similar to the temperature pH also increases the rate of reaction up to a maximum level and then declines the rate as every enzyme acts only at an optimum pH range.

Substrate concentration: If the substrate concentration is increased gradually while the concentration enzyme remains constant, the rate of reaction will increase until it reaches a maximum.
