What is phosphorylation ?

Answers

Phosphorylation:
phosphorylation is the formation of ATP by the addition of phosphate group to ADP...
there are two types of it
1 cyclic phosphorylation
2 non cyclic phosphorylation

Phosphorylation, binding organic molecule is a phosphate group.
Phosphorylation occurs differently-5:
Oxidative phosphorylation, ATP is formed by oxidation of foods pathway. Photophosphorylation, ATP production in cells of the light energy. In substrate level phosphorylation, ADP-phosphate group of a reactive intermediate with the transfer of a chemical reaction in which ATP is generated. Protein phosphorylation in proteins serine, threonine or tyrosine residues, via a kinase enzyme is the addition of a phosphate group. In chemistry, called organophosphate esters of phosphoric acid.

Describe what a limiting factor is and describe how each factor impacts the rate of photosynthesis.

Answers

A limiting factor is anything that constrains a population's size and slows or stops it from growing. these factors are mostly biotic . For example, Food or mates. Even competing for resources. Factors for the rate of photosynthesis range. The rate of oxygen output, carbon dioxide uptake, carbohydrate (glucose/sugar) production, temperature is also a limiting factor because At low temperatures, the rate of photosynthesis is limited by the number of molecular collisions between enzymes and substrates. At high temperatures, enzymes are denatured. As well as light intensity because without the sun it’s not even possible

Explain the connection between the oxidation of water in photosystem II of the light-dependent reactions and the synthesis of glyceraldehyde-3-phosphate in the light-independent reactions.

Answers

Answer:

Please find the explanation below

Explanation:

This question is describing the processes involved in photosynthesis. In the light-dependent stage of photosynthesis, specifically photosystem II (PSII), water is oxidized in a process called PHOTOLYSIS OF WATER. This process produces electrons and Hydrogen ions (H+). The electrons produced via this process is accepted by NAD+ to yield NADH.

The NADH is an electron carrier produced during the light-dependent stage and used to reduce 3-phsophoglycerate (PGA) produced in the light-independent stage to glyceraldehyde-3-phosphate (G3P).

Final answer:

The oxidation of water in photosystem II of the light-dependent reactions is connected to the synthesis of glyceraldehyde-3-phosphate in the light-independent reactions.

Explanation:

In photosynthesis, the oxidation of water in photosystem II of the light-dependent reactions is connected to the synthesis of glyceraldehyde-3-phosphate in the light-independent reactions. In the light-dependent reactions, photons of light strike photosystem II and excite electrons, which then pass through an electron transport chain, leading to the production of ATP and NADPH. The ATP and NADPH generated in the light-dependent reactions are then used in the Calvin cycle to power the synthesis of glyceraldehyde-3-phosphate from CO₂.

Greg and Andrea are trying to find out how long it takes amylase, a digestive enzyme found in saliva, to break down a sample of starch. They put their sample in a beaker and covered it with their own saliva. After allowing it to sit on the lab table for 1 hour they measured the remaining surface area of the starch. What is the best way they could improve their experiment?

Answers

The answer is: the amount of the saliva samples must stay consistent while the amount of starch must vary.

The amount of the saliva samples must stay consistent because amylase, present in the saliva, is the independent variable which affects the dependent variable - the amount of starch. So, amylase will do its job while remaining surface area of the starch will depend on the starting amount of the starch.

The relationship between a dependent variable and independent variable in a scientific investigation is that the dependent variable depends on the independent variable. You can also put it this way: The results depend on the factor of the experiment that differs from the controlled group.

This is why the best way they could improve their experiment is by taking consistent amounts of their saliva samples with varying amounts of starch.

I hope it helps, Regards.
