What is the relationship between water and enzymes in photosynthesis?

Answers

An enzyme in photosystem II splits water into hydrogen and oxygen. The energized electron is then passed along through another enzyme called the cytochrome b6-f complex, which in turn pumps positively charged hydrogen molecules across a membrane to create a store of potential energy.

All eukaryotic cells have a.
a covering called a membrane that surrounds the cell and controls what information and materials enter and leave it.
b. an internal fluid that gives shape to the cell and supports the other things within it.
c. a central zone or nucleus that contains the cell’s genes.
d. All of the above

Answers

Answer:

All eukaryotic cells have a membrane that covers them, internal fluid and a central nucleus, so the correct answer is option d (All of the above).

Explanation:

Eukaryotic cells are those that possess a plasma membrane that surrounds them, acting as a semi-permeable membrane to the passage of substances, in addition to possessing the capacity to receive external signals.

The cytoplasmic membrane of eukaryotic cells is related to an endomembrane system, associated to cytoplasmic organelles and to the central nucleus, which stores genetic information, in the form of DNA.

The eukaryotic cell cytoplasm is fluid and serves as a support for the organelles, as well as all the chemicals suspended in it.

The existence of true nucleus and organelles is what defines a eukaryotic cell and differentiates them from prokaryotic cells.

Why can’t two pyrimidines be paired with one anothr ?

Answers

Answer:

There are two reasons for this. The first reason is that the distance between the two strands of DNA is constant. Two purines together would be too big to fit in that distance, and two pyrimidines together would be too small. The second reason is that the bonding between purines and pyrimidines is very specific.

-)What must be present for the three stages of cellular
respiration to be exhibited?

Answers

Answer:

It needs oxygen in order to occur.

Explanation:

         Cellular respiration is this process in which oxygen and glucose are used to create ATP, carbon dioxide, and water; ATP, carbon dioxide, and water are all products of this process because they are what is created.

          The reactions of cellular respiration can be grouped into three stages: glycolysis (stage 1), the Krebs cycle, also called the citric acid cycle (stage 2), and electron transport (stage 3)

The other three stages of cellular respiration—pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation—require oxygen in order to occur.

What are some examples of non-cyclic changes.

If you can, please explain how they are noncyclic

Answers

Answer:

a change of seasons. a volcanic eruption. phase changes of the Moon. high and low tides.

Explanation:

Some examples of non-cyclic changes are volcano eruptions, the occurrence of tides, work done by an object, diffusion of liquids and gaseous compounds, fuel undergoing combustion, etc.

What are Non-cyclic changes?

Non-cyclic changes may be defined as the sequence of changes that are consistently involved but do not return the system back to its initial state. Irreversible processes are examples of non-cyclic changes.

Work done by an object is an example of a non-cyclic process because it is given by the area between the curve and volume axis. The noncyclic processes proceed in one direction only. This means that the product formed by these changes does not react together in order to reform the reactant again.

The fuel once burned will never get it again after combustion. Diffusion of liquids and gaseous do not form the initial products. Volcanic eruption forms molten lava which never occupies its initial stage.

Therefore, some examples of non-cyclic changes are mentioned above.

In humans, Mitosis organic process produced the cells named daughter cells.

In mitosis, nuclear division in eukaryotic cells occurs when a parent cell divides to provide two identical daughter cells.

There are two ways cellular division can happen in humans-

When a cell divides by way of mitosis, it produces two clones of itself, each with an identical number of chromosomes.

When a cell divides by way of meiosis, it produces four cells, called gametes.

What cells do mitosis the most?

 

Mitosis occurs whenever more cells are needed. It happens throughout the whole lifespan of a living organism (human, animal, or plant) but most rapidly in periods of growth. This means, in humans, the fastest rate of mitosis happens within the zygote, embryo, and infant stages.

Therefore, mitosis cell division produced daughter cells in humans.

Abe knew from his anatomy class that there are three different kinds of muscle tissue in the body. He knew lifting weights would help build the skeletal muscle and that running was good for cardiac muscle health. He was surprised to find out that his blood vessels had smooth muscle, so his exercise regimen was actually benefitting all the muscle types of his body. Correctly sort each of the characteristics into the appropriate category.

Answers

Answer:

Three different kinds of muscles are -:

SKELETAL MUSCELES CARDIAC MUSCLES SMOOTH MUSCLES

Explanation:

SKELETAL MUSCLES -: There are long, cylindrical, and striated skeletal muscle cells. They are multi-nucleated, which means they have more than one nucleus. This is because from the fusion of embryonic myoblasts, they are created. Each nucleus controls the sarcoplasm's metabolic demands around it. There are high energy requirements for skeletal muscle cells, because they contain several mitochondria in order to generate adequate ATP. Examples of skeletal muscles: arms and legs- The muscles that belong to the arms and legs feature in pairs. Abdomen and Back- These muscles are connected to the various sets of skeletal muscles that run across the torso.CARDIAC MUSCLES -: Cardiomyocytes have a short and narrow outline and are fairly rectangular. They are about 0.02 mm wide and 0.1 mm (millimetres) long, respectively. There are many sarcosomes in cardiomyocytes, which provide the required energy for contraction. Cardiomyocytes usually contain a single nucleus, unlike skeletal muscle cells. Cardiomyocytes, although they contain more sarcosomes, normally contain the same cell organelles as skeletal muscle cells. example - cardiac muscle is present in heart. SMOOTH MUSCLES -: Smooth muscle cells have a single central nucleus and are spindle-shaped. They range in length from 10 to 600 μm (micrometers), and are the tiniest type of muscle cell. In the expansion of organs like the kidneys , lungs, and vagina, they are elastic and therefore essential. As in cardiac and skeletal muscle, the myofibrils of smooth muscle cells are not aligned, meaning they are not striated, hence the term smooth. example of smooth muscles -: Walls of blood vessels ,  Walls of stomach , Ureters ,  Intestines ,  In the aorta (tunica media layer),  Iris of the eye. ,Prostate  and  Gastrointestinal Tract.

Soft tissues composed of long cells are called muscles. They are of various types like cardiac, skeletal and smooth based on their functions and locations.

What are the characteristics of the various muscles?

Skeletal muscles are cylindrical and striated muscles that have many nuclei and are voluntary. They have many mitochondria in them and have higher energy expenditure and generation. They are found in the arms, legs and abdomen region.

Smooth muscles are longitudinal and spindle-shaped muscles and are uninucleated. They are non-striated, lacks sarcomere and are elastic. They have the greatest capability of regeneration and are found in the intestines, eyes, stomach and many other organs.

Cardiac muscles are the muscles made up of cardiomyocytes and have many sarcomeres, and gap junctions for the coordinated contractions. The muscles are connected by intercalated discs and have rhythmicity. They are found in the heart.

Therefore, cardiac, smooth and skeletal are the types of muscles.
