lactic acid?
A The bacteria are breaking down sugars in the absence of oxygen.
B The bacteria are creating a H+ gradient to synthesize more ATP.
The bacteria are using their mitochondria to break down glucose in the presence of oxygen.
The bacteria are producing CO2 in the Krebs cycle that is then converted into lactic acid.
Answers
Answer:
A. The bacteria are breaking down sugars in the absence of oxygen.
Explanation:
Bacteria are microscopic single-celled organims. These organisms may produce their own source of chemical energy, or consume and absorb chemical energy made by producers.
They break down chemical energy like glucose through lactic acid fermentation in their cytoplasm, without the presence of oxygen.
In Glycolysis:
2 molecules of ATP are used to break up glucose into 2 molecules of pyruvate, 4 ATP and 2 electron carrying NADH molecules. Since 2 ATP are used, a net 2ATP are produced by this process.
Then, pyruvate is converted to lactic acid, producing 2 NAD+, used as electron carriers.
The option that best describes the process by which bacteria break down glucose to produce lactic acid is when bacteria break down sugars in the absence of oxygen. The correct option would, thus, be A.
Bacteria are capable of breaking sugars to generate energy, a process known as respiration.
This respiration can either be in the presence (aerobic) or absence (anaerobic) of oxygen.
Aerobic respiration has 3 major steps:
sugar is converted to pyruvates with the generation of ATP - glycolysispyruvates enter the Kreb's cycle to generate ATP and other molecules such as FADH2 and NADHFADH2 and NADH produced in Kreb's cycled are used to move electrons and generate energy in the electron transport chain.Both the 2nd and 3rd steps in aerobic respiration require oxygen and the summary of the entire process is in the following equation:
[tex]C_6H_1_2O_6 + 6 O_2 ---------> 6 CO_2 + 6 H_2O + ATP[/tex]
In the absence of oxygen, only glycolysis occurs and the pyruvates generated are quickly converted to lactic acid to generate a small amount of ATP according to the following equation:
Pyruvic acid + NADH <---> lactic acid + NAD+

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.

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.

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.
Wetland protection is one of the most controversial provisions of the ___________ because opponents believe that the legislation is _____________.A) Endangered Species Act; an infringement on their use of private property.
B) Clean Water Act; ineffective because it does not prevent pollutants.
C) Land Use Act; an infringement on their use of private property.
D) Clean Air Act; ineffective because it does not prevent pollutants.
E) Clean Water Act; an infringement on their use of private property.
Answers
Answer:
The correct answer is - option E. Clean Water Act; an infringement on their use of private property.
Explanation:
Section 404 of the clean water act has the regulation or provision for wetland protection which has the primary aim to protect and preserve the area near the water such as swamp, bogs, and wetlands.
This is the most controversial provision of the CLean water act as most of the wetlands area on private property or private land which does not allow to use their private property according to the will and which is considered as an infringement on their use on private property.
