What is the chemical reaction that lactase catalyzes?

Answers

Answer:

galactose and glucose

Explanation:

Lactase catalyzes the hydrolysis of the glycosidic bond in the disaccharide lactose, releasing galactose and glucose hope this worked :)

The chemical reaction that is catalyzed by the enzyme lactase is the breakdown of lactose into glucose and galactose. The reaction is as follows:

Lactose → Glucose + Galactose. (in the presence of Lactase).

What is a Chemical reaction?

A chemical reaction may be defined as a process through which one or more substances known as the reactants are significantly transformed into one or more different substances known as the products in the presence of enzymes of energy.

Lactose is a type of disaccharide which dissociates into glucose and galactose. It is similar to maltose which in presence of an enzyme maltase gives two different compounds of glucose and sucrose in presence of an enzyme sucrase converts into glucose and fructose.

Therefore, the chemical reaction that is catalyzed by the enzyme lactase is the breakdown of lactose into glucose and galactose.

Answers

Answer:

Increasing  carbon dioxide  concentration  increases the  rate of  photosynthesis  as carbon  dioxide (CO2) is a limiting factor.

Explanation:

Some limiting factors like carbon dioxide, temperature etc. influence the photosynthetic rate, which may end up reducing the potential amount of carbohydrate produced by photosynthesis. Carbon dioxide is important for this form of biosynthesis: it provides the inorganic carbon that is integrated into carbohydrate molecules.

The photosynthetic rate can be slowed by a decline in the concentration of available carbon dioxide.

6 CO2 + 6 H2O + light  →  C6H12O6 + 6 O2

Carbon Dioxide + Water + Light       Glucose + Oxygen

Stagnant, shallow areas of water-saturated soil, where the rate of photosynthesis is low, are best characterized as:______.

Answers

Answer:

The correct answer is - bogs.

Explanation:

Bogs or boglands is a wetland that is made up of dead organic matter such as dead plants or parts of the plants like mosses, majority time it is a thick carpet of sphagnum moss. All these form spongy peat which is stagnant.

Most of the water present in this wetland comes from rainfall instead of runoff or streams from the groundwater which makes it a wetland with a shallow area of water-saturated soil. This wetland is known for its less photosynthesis.

In your Punnett Square activity, you chose beads which represented
genes and used Punnett Squares to determine possible offspring. If
your first parent genotype was yellow bead and blue bead and the
second parent genotype was blue bead and blue bead, how many
offspring out of 4 have the yellow kernel phenotype?
please please!!

Answers

Answer:

Two out of four offsprings have the yellow kernel phenotype.

Explanation:

The information that we have is that one parent's genotype is yellow bead (Y) and blue bead (B), and the other parent's genotype is blue bead (B) and blue bead (B).

Parent 1: YB

parent2: BB

If we make a Punnett Square, we can see that two out of four offspring will have the yellow phenotype.

  ║ B   ║ B   ║

Y║ YB ║ YB ║

B ║ BB  ║ BB ║

The offspring out of 4 have the yellow kernel phenotype in the given case would be - two or 50%

We are given that the kernel color is represented by two beads, yellow and blue beads.

Let us consider yellow bead be represented as Y and blue bead be represented as y. Yellow color is dominant over blue kernel color.parent 1 has a genotype of a yellow bead and a blue bead represented as Yy.parent 2 has a genotype of the blue bead and blue bead, i.e, yy.

The cross can be given as,

Genotype Y y

y   Yy     yy

y    Yy     yy

Now, two of the four offspring have Yy genotypes.

Thus, 2/4 or 50% of the offspring have a yellow kernel phenotype.

Chlorophyll, cell wall and vacuole, chloroplasts, and mitochondria are used to fill in the blanks.

What are cell organelles?

An organelle is a subcellular structure that, like an organ, has one or more specific jobs to do in the cell.

The organisms that comprise the pigment chlorophyll convert the energy from light into chemical energy that can be stored in the form of sugars through the process of photosynthesis.

The cell wall and vacuoles found in plant cells aid in the preservation of shape and integrity.

Chloroplasts are plant organelles that work to store pigments and food. It stores pigment, specifically chlorophyll, which converts light energy into chemical energy.

The mitochondria convert food into usable energy through the process of cellular respiration. The mitochondria, which are found in all plants and animals, are thought to be converters.
