Plants respire all the time, whether it is dark or light, because their cells need energy to stay alive. But they can only photosynthesize when they have light.
The oxidation of water occurs during photosynthetic electron transport during the light reactions of photosynthesis. In the absence of a source of light energy (dark reactions have no direct requirement for light energy), oxygen is not produced.

Why was the evolution of cyanobacteria such a significant event in Earth's history?
Answer:
Cyanobacteria are blue-green algae that produce chlorophyll and undergo photosynthesis. Oxygen, a byproduct of that photosynthesis, was released into the atmosphere, changing it in such a way that it may have allowed the evolution of more complex forms of life.

Figure 11-1
In which part of the cell does this process shown in Figure 11-1 take place?
Answer:
The correct answer is - in the ribosomes.
Explanation:
The translation is the process that takes place in the ribosomes attached to the endoplasmic reticulum where they decode the codons present in the form of the mRNA to the amino acid chain with the help of tRNA.
Ribosomes are called the factory of the protein. It involves triplet code to translate into the amino acid sequences to produce polypeptide chains or protein.
Thus, the correct answer is - in the ribosomes.

In gout, both serum and synovial fluid will have increased levels of:
In gout, both serum and synovial fluid will have increased levels of uric acid.
Gout is a type of arthritis characterized by the accumulation of urate crystals in joints, which leads to inflammation and severe pain. Uric acid is a natural byproduct of purine metabolism in the body.
Normally, uric acid is dissolved in the blood and excreted through the kidneys. However, in individuals with gout, there is either an overproduction of uric acid or a decreased ability to excrete it, resulting in elevated levels in the bloodstream.
The excess uric acid can precipitate and form crystals in the synovial fluid, which is the lubricating fluid found in joints. These crystals trigger an inflammatory response, causing pain, swelling, and redness characteristic of gout attacks.
The deposition of urate crystals in the synovial fluid can be confirmed by analyzing the fluid obtained through joint aspiration.
Furthermore, since uric acid is elevated in the bloodstream, it is also reflected in the serum levels. Blood tests can measure the serum uric acid levels to aid in the diagnosis of gout.
Therefore, in gout, both serum and synovial fluid will have increased levels of uric acid, reflecting the underlying metabolic imbalance in purine metabolism.

question 62 80) a reduction in the amount of nadp available in plant cells in the light will ultimately result in a) an increase in the rate of the calvin cycle. b) a decrease in the rate of linear electron flow. c) a decrease in the rate of cyclic electron flow. d) an increase in the rate of oxygen production.
A reduction in the amount of NADP available in plant cells in the light will ultimately result in a decrease in the rate of linear electron flow. This is because the linear electron flow depends on the availability of NADPH which is the reduced form of NADP (nicotinamide adenine dinucleotide phosphate) and ATP that are produced during photosynthesis so the correct answer is option (B).
NADPH plays a crucial role in the Calvin cycle by providing energy in the form of high-energy electrons that are used in carbon fixation. The electrons are transferred from NADPH to CO2 to form carbohydrates, and in the process, NADPH is oxidized to NADP. In the absence of NADPH, the Calvin cycle would not be able to proceed at a normal rate. ATP is also required by the Calvin cycle to provide the energy required to power the various enzymatic reactions that take place during carbon fixation.In the presence of light, photosynthesis occurs in two stages: the light-dependent reactions and the light-independent reactions.
The light-dependent reactions occur in the thylakoid membranes of chloroplasts and involve the conversion of light energy into chemical energy in the form of ATP and NADPH. Linear electron flow is the primary pathway that produces ATP and NADPH during photosynthesis. It involves the transfer of electrons from water to photosystem II, through the cytochrome b6f complex, and on to photosystem I before finally being transferred to NADP+. Cyclic electron flow also occurs in photosynthesis but produces only ATP. In cyclic electron flow, the electrons are recycled back to the cytochrome b6f complex instead of being transferred to NADP+.
Therefore, a reduction in the amount of NADP available in plant cells in the light will ultimately result in a decrease in the rate of linear electron flow.

Explanation:
1) Reflection is when a ray hits something reflective then bounces back. For example, light reflects off a mirror, which is why you can see yourself in a mirror.
2) Wavelength measures the size of a wave. It is measured from the crest or trough of one wave to the crest or trough of another.
3) Refraction occurs when waves go through different mediums at different speeds. This is why a straw looks bent when in water.
4) Frequency is a way of measuring the speed of a wave. It shows how many waves pass every unit of time.
5) Absorption means that all of the waves were absorbed into the medium and none of them passed through.
