exposing plants to the green light reduces starch creation as green light is mostly reflected and not absorbed by chlorophyll, leading to almost minimal photosynthesis. blue light is absorbed by chlorophyll and supports photosynthesis, but it doesnt provide the whole colour spectrum like white light, the rate of starch formation is lower than under white light. white light contains all all colour wavelengths including blue, which maximizes photosynthesis and starch production.

Exposing green light to the plant leads to the chlorophyll reflecting the green light rather than absorbing it leading to low photosynthesis and therefore less starch formed. Exposing the plant to blue light leads to more light being absorbed, therefore high photosynthesis and more starch being formed. In white light, both red and blue light are absorbed and therefore produces the highest amount of photosynthesis and most starch

The plant is most likeyl a c4 plant. its characteristics state that it follow the c4 pathway and calvin cycle like the c4 and cam plant compared to, ensuring it isnt a c3 plant. It also has an open stomata during the day. this is a key feautre isolating it from the fact that its not a CAM plant as they do not let in CO2 during the day. Water loss is moderate during the day, similarly shown through the c4 plant. Additionally, the plant holds an ptimum temperature quite above the c3 plant its compared to, and within the c4 plants range

The unknown plant is most likely to be a c4 plant since the unknown plant has the ideal temperature for photosynthesis at 25-35 degrees while c4 plants ideal temperature is 30-40 degrees. The unknown plant also uses the c4 pathway and Calvin cycle to fix co2 as well as c4 plants. The unknown plant and c4 plants both have their stomata open during the day. Photorespiration occurring is low for both the unknown and c4 plants. Water loss during the day is moderate for both the unknown and c4 plants. Plant growth rate is moderate for the unknown but fast for c4, but this difference could be due to external factors such as the amount of sunlight provided to the plant.

C4 Plant, it lives in hot environments where temp is 25-35, it uses c4 pathway and Calvin cycle for carbon fixation, it’s stomata is opened during the day, photorespiration occurs low to moderate suggesting that it has adapted to prevent photorespiration suggesting it is a c4 plant. Overall we can say it is a c4 plant because stomata is opened during day so it’s not Cam plant, photorespiration occurs low, it’s not a c3 plant.

The unknown plant is a c4 plant

It uses the c4 pathway and Calvin cycle, like C4 plants.
Its ideal temperature for photosynthesis 25-35 degrees
It has stomata open during the day which confirms its not a cam plant. The plant also show moderate to low photorespiration which proves that its not a c3 plant.
It also has moderate water loss

Coenzymes help transfer energy and electrons during glycolysis. For example, NADPlus and FAD pick up hydrogen ions and electrons during glycolysis and the Krebs cycle, becoming NADH and FADH2. These loaded coenzymes then carry the electrons to the ETC, where most of the ATP is produced. So they are responsible for energy transport.

ATP is produced through aerobic cellular respiration. Conezymes involved in aerobic cellular respiration involve NAD+ and FAD, which roles during glycolysis and Krebs cycle is to accept electrons and hydrogen molecules from the breakdown of glucose in order to become charged NADH and FADH. After becoming charged they transport to the electron transport chain at the cristae.

The role of coenzymes in the formation of ATP happens during the electron transport chain. Coenzymes NADH and FADH2 unload their chemical energy and break down alot of hydrogen ions. This results in the increase of acidity in the mitochondrial matrix. The concentration gradient is facilitated by ATP synthase which channels the hydrogen ions into the intermembrane. ATP synthase gets charged up and turns adp+pi to ATP.

The results are the same in the presence and absence of oxygen since anaerobic cellular respiration is occurring in the red blood cells.

This is due to the absence of a mitochondria in red blood cells, which is an organelle required for aerobic respiration to occur, therefore anaerobic respiration takes place

Therefore the rate glucose consumed and lactate produced is the same, since oxygen is not a factor affecting anaerobic respiration.

They cant use oxygen for energy because red blood cells dont have mitochondria. They break down glucose either way with or without oxygen.

2025-05-05 07:47:59 UTC

Red blood cells don’t have mitochondria, so they can’t do aerobic respiration, even when oxygen is present. So they always rely on anaerobic respiration to produce energy. This means that glucose is broken down into lactic acid regardless of oxygen availability. That’s why the amount of glucose used and lactic acid produced stay the same whether oxygen is there or not.

The results are the same irrespective of the presence of oxygen because red blood cells do not have mitochondrias. This means that both have to undergo anarobic respiration as glycolosis happens in the mitochondria
