what molecule makes instructions for proteins and is located inside a eukaryotic nucleus
Answers
Answer:
DNA stores that info
Explanation:
In eukaryotic cells (ex. plants and animals) the DNA is found in the nucleus of the cell. Structures called ribosomes build proteins (this process is called translation).
The molecule that is responsible for carrying the instructions for the formation of protein is mRNA, which is formed inside the nucleus.
The mRNA is known as the messenger RNA because it acts as a messenger, to carry the instructions required to create a polypeptide chain.
The mRNA is formed during the process known as transcription. The mRNA is formed by the molecule known as RNA polymerase.
During the process of transcription, the genetic information gets copied as a strand of nucleotides containing adenine, uracil, guanine, and cytosine, known as mRNA, which is formed inside the nucleus.
The molecule which act as a carrier of the genetic information for the formation of proteins is known as mRNA.

C- Cell membrane
D- Golgi bodies
E- Smooth and rough endoplasmic reticulum
F- Cell wall
Explanation:
This is a structure of a plant cell which unlike animal cell has a cell wall as well as plasma membrane. It also contains large vacuoles present in the center of the cell. The green color of the plants is due to the presence of chlorophyll which is present in an organelles called chloroplast.
Organelles which are labelled in the cell are
A:Cell membrane
B:Vacuole
C:Nucleus
D:Cytoplasm
E:Chloroplast
F:Cell wall
The given figure represents a plant cell. So, the correct option is C.
What is Plant cell?Plant cells are defined as eukaryotic cells that contain a true nucleus as well as specialized structures known as organelles that perform certain specialized functions. Plant and animal cells both contain a nucleus with similar organelles but plant cells differ due to the presence of a cell wall outside the cell membrane.
In the given figure, labelled organelles function are as follows:
Vacuole stores food, extra water, and waste while cell membrane permits selective passage of things into and out of the cell. The cell's nucleus serves as the activity's control centre, while the cytoplasm is the fluid that gives the cell its jelly-like consistency. Chloroplasts contain a substance called chlorophyll that is a green pigment that aids in photosynthesis. The cell wall of a plant gives it form, stiffness, strength, and protection.
Thus, the given figure represents a plant cell. So, the correct option is C.

Three types of macromolecules are mentioned in the video that are digested and ABSORBED in the small intestine. What do they all get absorbed into first?
Lacteals
Epithelial cells
Capillaries
Answers
Given what we know about the biology of the small intestine, we can confirm that the macromolecules are being absorbed into the "Epithelial cells".
The small intestine is in charge of absorbing the nutrients, which we require in order to survive and perform even the most basic metabolic processes, from the food that we ingest. In order to be able to perform this function, the cells in question have specialized epithelium which consists of Microvilli.
Microvilli can be thought of as membrane protrusions that serve to expand the surface area of the epithelial cells. This allows the cells to have a greater area through which to absorb nutrients such as the macromolecules mentioned.

enzymes are specific they will only fit with certain substrates explain why lactase can digest lactose but cannot digest other sugars like maltose and sucrose
Answers
Explanation:
your small your small intestines can't absorb either lactose or maltoseyou use different enzymes to digest the two sugars lactase break down lactose why an enzyme called sucrase-isomaltase breaks down maltose because enzyme are so specific with regard to function you can't break down maltose with lactose or vice versa
Lactase breaks down only lactose in food in our body can absorb it not maltose and sucrose as enzymes are specific in nature.
what are the properties of an enzyme ?Enzymes are protein which act as a catalysts and speed up the rate of biochemical reactions with out changing the structure of the final product.
Enzymes can control the speed and specificity of the chemical reaction, and the rate of biochemical reaction often influences enzymes and they can take place at a relatively low temperature; it lower the activation energy.
The enzyme activity pH specific, that is at a particular pH, each catalyst is most active for example at PH 2 for pepsin, pH 8.5 for trypsin, for example.
Both enzymes have active sites which can activate biochemical reactions. It is soluble in water, dilute glycerol, NaCl, and dilute alcohol.
