Task
Lactic acid Alcohol fermentation Lactic acid fermentation is a metabolic process that converts glucose into the metabolite lactate as well as cellular energy. The metabolic process of glucose conversion to ethanol and carbon dioxide is known as alcoholic fermentation.
They are both types of anaerobic respiration
Pyruvate is converted into lactic acid molecules. From the pyruvate molecule, ethanol and carbon dioxide are produced. They break down glucose molecules into two pyruvate molecules
Question 2
2.1 The light reaction takes place in the thylakoid membrane.
The Calvin cycle takes place in the stroma of the chloroplast.
2.2 Glucose and oxygen gas
2.3 The initial stage of photosynthesis is the light reaction, which converts solar energy into chemical energy in the form of ATP and NADPH. NADPH and ATP are produced with the help of protein complexes and pigment molecules.
The following is a description of the light reaction process:
Light energy is collected by the pigment chlorophyll and transformed into chemical energy in the form of electron charge carrier molecules like NADPH and ATP in light reactions.
Both Photosystems I and II, which are found inside the chloroplasts’ thylakoid membranes, use light energy. Carbon dioxide is converted into carbohydrate molecules with the help of chemical energy acquired throughout the processes.
The light energy splits into the water and removes the electrons from photosystem II; the electrons then go from PSII to b6f (cytochrome) to photosystem I (PSI) and diminish in energy form.
In Photosystems I, electrons are re-energized, and high-energy electrons convert NADP+ to NADPH.
In non-cyclic photophosphorylation, the cytochrome uses electron energy from Photosystem II to transfer hydrogen ions from the lumen to the stroma; this energy then allows the ATP synthase to attach to the ADP molecule’s third phosphate group, forming ATP.
During cyclic photophosphorylation, the cytochrome b6f utilises electron energy from both Photosystems I and II to build a number of ATP while stopping the creation of NADPH, ensuring that the correct amounts of ATP and NADPH are maintained.
Thus, light reactions use light energy to drive electron transport and proton pumping, converting the energy from light into the biologically useful form ATP and producing a viable source of reducing the power NADPH.
Question 3
3.2 Interphases and mitotic (M) phase
3.3The G1 checkpoint is located at the G1/S transition. It is at this stage a cell must decide whether of not to divide.
The G2 checkpoint is located at the G2/M transition, where the cell checks for DNA integrity and DNA replication.
The spindle checkpoint is located at the metaphase to anaphase transition. The cell checks to see if all of the sister chromatids are connected to the spindle microtubules appropriately.
Question 
T2 was first grown with E. coli in a solution containing radioactive sulfur by Hershey and Chase. Sulfur is found in protein but not in DNA, therefore when new phages were created, the radioactive sulfur atoms were only absorbed into the protein. The bacteriophage’s proteins A second plant was grown by the researchers.
Phages in a solution containing radioactive phosphorus in a batch Due to the fact that practically all phages are because phosphorous is found in DNA, this only labelled the phage DNA. Hershey and her team were armed with two batches of labelled T2. Chase was all set to carry out the experiment depicted in They let the two batches of T2 infect one other. Non-radioactive bacteria samples should be separated
They stirred the cultures in an ordinary kitchen mixer shortly after infection began to shake loose any pieces of the phages that remained outside the bacterial cells. The mixes were then collected in tubes and spun in a centrifuge. The cells formed a solid pellet at the bottom of the centrifuge tubes, while phages and fragments of phages remained suspended in the liquid because they were lighter. The radioactivity in the pellet and the liquid was then measured.
When bacteria were infected with T2 phages bearing labelled protein (batch 1), Hershey and Chase discovered that the radioactivity was mostly concentrated in the solution within the centrifuge tube, which included phages but not bacteria. This indicated that the phage protein was not able to enter the cells. However, when the bacteria were infected with phages containing DNA tags (batch 2), the majority of the radioactivity was found in the bacterial cell pellet at the bottom of the centrifuge tube. Furthermore, when these bacteria were placed in a liquid growth media, they quickly lysed or burst open, releasing new phages with radioactive phosphorus in their DNA.
