If I put a potato in ammonia (a base) then the activity of catalase will decrease because the pH level will be to basic for any catalytic (catalase) activity.
Hope this helps! Please correct me if I'm wrong :)
If I put a potato in ammonia (a base) then the activity of catalase will decrease because the pH level will be to basic for any catalytic (catalase) activity.
What is catalase?An enzyme called catalase causes (catalyzes) the process by which hydrogen peroxide is broken down into water and oxygen.
Catalase, which is widely distributed in organisms that live in the presence of oxygen, inhibits the buildup of peroxide, which is continuously created by multiple metabolic reactions, and shields cellular organelles and tissues from harm. Catalase is primarily found in the liver of mammals.
Therefore, If I put a potato in ammonia (a base) then the activity of catalase will decrease because the pH level will be to basic for any catalytic (catalase) activity.

describe the organization of skeletal muscle at tissue level
The organization of skeletal muscle at tissue level is made up of:
• Epimysium; around the muscle belly.
• Perimysium; surrounding the muscle fascicles.
• Endomisium; coating the muscle fibers, which in turn, are made up of myofibrillar structures.
The muscle cell or fiber is the structural and functional unit of muscle tissue. The skeletal muscle tissue has a striated appearance.
Muscle fibers are organized in bundles surrounded by an outer connective tissue membrane, called the epimysium.
Very thin septa of connective tissue start from this, which are directed towards the interior of the muscle, dividing it into fascicles, these septa are called perimysium.
Each muscle fiber is surrounded by a very thin layer of reticular fibers, forming the endominsium.
The connective tissue holds the muscle fibers together, allowing the contraction force generated by each individual fiber to act on the entire muscle, thus contributing to its contraction.
Therefore, we can conclude that the organization of skeletal muscle at tissue level of the striated muscle fibers is given by the connective tissue that is organized in: Endomysium, Perimysium and Epimysium.

In one to three sentences, describe what happens during the reduction stage of the Calvin cycle
Answer:
ATP and NADPH transfer chemical energy to 3-PGA.
Glyceraldehyde 3-phosphate (G3P) is created.
G3P is used to make sugar.
Explanation:
edge 2020
i'm just different
During the reduction stage of the Calvin cycle, the 3-PGA molecules produced by carbon fixation are transformed into simple sugar molecules – glucose.
In this step, the energy is supplied by the ATP and the NADPH produced during the light-dependent photosynthesis reactions.
ATP, or NADPH, is used to transform the 3-PGA molecules into three-carbon sugar molecules (G3P molecules). The name “G3P” comes from the fact that NADPH gives electrons to, or breaks down, a 3-carbon intermediate to form G3P.
Carbon dioxide in the atmosphere undergoes a redox reaction to glucose. This redox reaction requires the total reduction of CO2 using the electrons available in the oxidation of the NADPH. Thus, the dark reactions are a redox pathway. Calvin-Benson cycle.

In the tonicity of red blood cells lab, if you had chosen the strategy "I will measure The volume changes to the solution added to the red blood cells before and after the treatment to see if the amount of solution changes," would this be an effective strategy? Why or why not?
Answer:
The correct answer is No.
Explanation:
Measuring the volume change after placing:
In a hypertonic solution - solvent moves outside of the cell and the cell shrinks, the change in volume of solvent would be very minute to observe or measure as the RBCs are very small cells.
in a hypotonic solution - the change in the solvent or solute or overall solution is very less and will be very insignificant to come to any result. The water volume change would be difficult to measure.

Special lymphatic vessels, called lacteals, absorb dietary __________ that are not absorbed by the blood capillaries.
Answer:
This question lacks options, options are:
A. water
B. glucose
C. vitamins
D. amino acids
E. lipids
The correct answer is E.
Explanation:
Lipids are a heterogeneous group of organic compounds divided into fats or oils, phospholipids and cholesterol esters. The lymphatic vessels are responsible for the transport of lipids and fat-soluble vitamins (A, D, E and K), which are absorbed through the digestive tract, that is, they act as capturers of fats and excess fluids from the human body, always present in the blood vessels. They do not carry blood, but lymph, a clear liquid. They play an important role in the transport of fats, in the recovery of fluids that escape from the blood capillaries and in the fight against infections. In the small intestine, specialized lymphatic capillaries transport lipids from the diet to the lymphatic vessels and, ultimately, to the blood. The presence of these lipids makes the lymph drained through the small intestine appear creamy white.
Cyclic AMP phosphodiesterase is an enzyme that catalyzes the conversion of cyclic AMP to a different molecule. Which of the following best predicts the effect of inhibiting cyclic AMP phosphodiesterase in a muscle cell stimulated by epinephrine?
The concentration of cyclic AMP will decrease because adenylyl cyclase will no longer be activated.
The G protein will diffuse out of the cell because it will no longer bind to the plasma membrane.
Phosphorylase kinase will remain active because protein kinase A will no longer be deactivated.
Glycolysis will stop because epinephrine signaling will no longer stimulate glycogen breakdown.
Answer:
Phosphorylase kinase will remain active because protein kinase A will no longer be deactivated.
Explanation:
Phosphodiesterase is an enzyme that has the function of hydrolyzing cAMP by converting it to AMP. As a result, a protein called kinase is inactivated and lipids break down in fat metabolizing cells. CAMP is a cellular messenger. Cyclic AMP phosphodiesterase, in turn, is an enzyme that catalyzes the conversion of cyclic AMP into a different molecule. as a result, a molecule called kinase A is deactivated. However, if inhibition of cyclic phosphodiesterase AMP in a muscle cell stimulated by adrenaline, Kinase A will not be deactivated, so phosphorylase kinase will remain active.

Photorespiration lowers the efficiency of photosynthesis by removing which of the following from the Calvin cycle?
a. ATP molecules
b. carbon dioxide molecules
c. ribulose bisphosphate molecules
d. RuBP carboxylase molecules
e. glyceraldehyde phosphate molecules
Answer:
Option B.
Carbondioxide molecules.
Explanation:
Photorespiration lowers the efficiency of photosynthesis by removing carbondioxide molecules because photorespiration begins in Calvin circle as a result of Rubisco acting on oxygen instead carbondioxide and it's function is to first initiate and input carbondioxide in Calvin circle. Therefore instead of using Carbondioxide as the pathway , it uses oxygen. Carbondioxide is use for photosynthesis because it combine with water in the presence of light energy and chlorophyll to produce glucose and oxygen.

Encyclopaedia Britannica's editors oversee subject areas in which they have ... from intrusive rocks on the basis of their texture and mineral composition
Explanation:
The presence of a layer of extrusive rocks is due to a single volcanic eruption and its presence in the middle of a rock formation may be because these rocks are younger than the surrounding rock formations.
What are extrusive rocks?The presence of a layer of extrusive rocks in the middle of a rock formation refers to the geological history of the area. These rocks are formed from lava that has been erupted from a volcano and cooled quickly on the Earth's surface followed by the cooling at the surface of the Earth. This suggests that a volcanic event has occurred in the area.
When a volcanic eruption occurs, lava is ejected from the volcano and flows onto the Earth's surface followed by its solidification into extrusive rocks which have fine-grained texture.
The presence of extrusive rocks in the middle of a rock formation may be due to a single volcanic eruption or these rocks are often younger than the surrounding rock formations.
Therefore, the presence of extrusive rocks is due to a single volcanic eruption and may be younger than the surrounding rock formations.
