The two organelles involved in cellular energetics are mitochondria and chloroplasts. While both organelles are involved in cellular energetics, they are only found in specific types of cells.
Mitochondria are found in both animal and plant cells, whereas chloroplasts are only found in plant cells. Organelles are specialized structures present inside cells that perform specific functions.
These functions can include metabolism, transport, and protection. Organelles are generally membrane-bound, meaning they are surrounded by a membrane that separates their internal components from the rest of the cell. Organelles work together in a coordinated fashion to maintain the overall health and function of the cell.
Cellular energetics refers to the processes by which cells obtain and utilize energy. This energy is used for a variety of functions, including movement, growth, and reproduction. The two organelles most closely associated with cellular energetics are mitochondria and chloroplasts.

not enough of a sample.
contaminated samples.
degraded samples.
All of the above.
Answer: Option D " all of the above "
Explanation: DNA can be a great source of information when used as a forensic evidence. This technique has many advantages and disadvantages when used as a source of information in case of crime.
Identical twins: There are some common fragments of DNA that is same in identical twins so it can be a difficulty in deciding the criminal.
Not enough of a sample: DNA should be present in a detectable amount to be used an sample for evidence, less than this detectable amount is a waste and cannot be used as a sample for evidence.
Contaminated and degraded sample: If the sample of DNA is contaminated or degraded then the result might be incorrect and might not be used as a sample for forensic evidence.
Hence, the correct answers are all of the above.
Answer:
There will be no movement of kinesin motor protein along the microtubules .
Explanation:
Microtubules is an important component of cytoskeleton which play an important role in maintaining cell shape,cell motility,cell division regulation etc.
Whereas kinesin belongs to the family of motor proteins present in the eukaryotic cell.Kinesin plays an important role axonal transport.
The hydrolysis of ATP generates energy to power up the movement of kinesin along the microtubules.
According to the given question if kinesin and microtubules were incubated with an non hydrolyzable ATP analog instead of ATP,then the movement of kinesin along the microtubules will not occur due to lack of energy because the non-hydrolyzable analog of ATP cannot undergo hydrolysis to release energy.
Answer: Diffusion
Explanation:
The osmosis is explained as the selective permeability of the membranes which allows the movement of the solute from higher concentration to lower concentration.
This is associated with diffusion which can be defined as the random movement of the particles in order to attain equilibrium.
The diffusion allows the movement of the particles and osmosis allows the movement of only selective materials.

Chloroplast is the site for photosynthesis in plants. Thus, option A is correct.
Chloroplasts are the cell organelles present in the plants. Chloroplasts are one such type of plastids.
Chloroplasts are green in colour. They contain a green coloured pigment called chlorophyll which traps the solar energy.
The solarenergy is converted into chemicalenergy by a process called photosynthesis. The organic molecules so produced are the energyrich compounds.
Chloroplasts are chiefly found in the mesophyll region of the leaves.
Chloroplast consists of grana and stroma regions. The grana contain disc shaped coin like structures called thylakoids. The matrix of chloroplasts constitutes stroma region.
Various enzymes, DNA, ribosomes etc are found within the chloroplasts. Hence, they are also referred as 'cellwithinthecell'.
Chloroplasts have unique feature of self-replication. Chloroplasts are similar in function to mitochondria in animal cells.
Therefore, chloroplasts are important plant structures for photosynthesis.

In plants, photosynthesis takes place in chloroplasts. Option A is correct.
Plant, algae, and certain protist cells have membrane-bound organelles called chloroplasts.
So, They are in charge of the process known as photosynthesis, which turns light energy into chemical energy in the form of glucose in green plants and some other animals. Life on Earth is supported by this essential mechanism of energy conversion.
Therefore, In plants, photosynthesis takes place in chloroplasts.

3. What is the standard free energy change of the reaction above? Again, define each term.
Answer:
Explanation:
From the reaction ; aA + bB → cC + dD
1) Keq = equilibrium constant = [A]^a [B]^b / [C]^c [D]^d
where [A] = [B] = [C] = [D] are the concentrations of reactants A, B, C and D respectively.
2) What is the actual free energy change of the reaction above? ;
where R = gas constant and T = temperature.
3) What is the standard free energy change of the reaction above;
