~ The higher the rate of formation of products in respiration, the lower the rate of photosynthesis.
~ Photosynthesis depends on the carbon dioxide released during cellular respiration.
~ Cellular respiration depends on the water released during photosynthesis.
~ They have the same set of product molecules.
Photosynthesis depends on the carbon dioxide released during cellular respiration. Option C.
Glucose is then converted to carbon dioxide and used for photosynthesis. Water is broken down into oxygen during photosynthesis, but oxygen combines with hydrogen during cellular respiration to produce water. Cellular respiration is the process by which biofuels are oxidized in the presence of inorganic electron acceptors
Most aerobic respiration with oxygen occurs in the mitochondria of cells whereas anaerobic respiration without oxygen occurs in the cytoplasm of cells. During cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as by-products. In the absence of oxygen, pyruvate undergoes a process called fermentation.

Where does soil erosion occur?
Application: The enzymes in lysosomes are dangerous, and can’t be directly exposed to the cytoplasm. In the diagram
below, 7 represents a lysosome. Explain what has to happen for an enzyme to get placed inside a lysosome. Note that the
membrane (8) is not involved in this process.
First, the instructions…
Next,
After that, the smooth ER will
Following that, a vesicle will
At the Golgi,
Finally.
First, enzyme synthesis occurs following mRNA instructions. Next, enzymatic maturation occurs in the RER. After that, the SER sends enzymes and lipids to the Golgi complex into vesicles. The Golgi complex packages hydrolytic enzymes into lysosomes and sends them to thei destiny.
How are lysosomal enzymes synthesized and packaged?Let us remember that enzymes are proteins, so they follow the protein synthesis process.
1)
First, mRNA is synthesized within the nucleus by copying the DNA fragment that provides the necessary information for protein building.
2)
When mRNA leaves the nucleus forward to the cytoplasm, it meets a ribosome and starts protein-building. Ribosomes attached to the RER membrane are responsible for synthesizing membrane proteins, exportation proteins, or enzymes.
Proteins destined to become enzymes, membrane proteins, or exportation proteins start their growth in the cytoplasm, where a signal aminoacidic sequence is synthesized.
A signal-recognizing particle leads the synthesizing protein to the Rough endoplasmic reticulum. Once there, it continues protein building forward the reticulum lumen.
When the new protein synthesis is complete, the polypeptide is released into the reticulum lumen, suffering a few posterior steps related to conformation and structure.
The rough endoplasmic reticulum is in charge of protein folding to become functional, maturation, and transport. It produces the latest protein modifications after transduction and initiates the glycosylation process.
3)
Meanwhile, the smooth endoplasmic reticulum is in charge of lipid synthesis. These lipids are the ones that will compose the vesicle membranes in which proteins are packaged and the lysosome membranes.
4)
The new proteins get packaged into vesicles that carry them to the Golgi complex. Lipids are also sent to the Golgi complex.
5)
Once in the Golgi complex, occurs the final association of carbohydrates and lipids with proteins to originate glycoproteins and glycolipids.
This distribution center sends proteins to different regions in the cells. Among other functions, it concentrates and packages hydrolipic enzymes into lisosomes.
6)
Enzymes are packaged and sent from the Golgi complex to their final destiny into vesicles. Lisosomes are formed.
So, according to this sequence, we can answer the question.
First, the instructions for enzyme synthesis will be copied from DNA in the nucleus, where mRNA is synthesized.Next, mRNA will leave the nucleus. Enzymes synthesis will start in the cytosol and finish in the rough ER. The enzyme maturation stage will be completed there.
After that, the smooth ER will produce membrane lipids, and package the enzymes into vesicles.
Following that, a vesicle will reach the Golgi complex.
At the Golgi, hydrolytic enzymes will be packaged into lysosomes.
Finally, lysosomes will be released into the cytosol to accomplish their functions.

Alcoholic Fermentation
Amino Acid Synthesis
Previous
Lactic Acid Fermentation is the processes we would expect to be key in the production of yogurt.
Fermentation is a natural process that can be used in a number of ways for wide variety of food products. Yogurt forms when bacteria ferment the milk sugar, known as lactose, into lactic acid. The lactic acid makes the milk more acidic (lower pH) causing the proteins to coagulate.
Yogurt is a product of the acidic fermentation of milk. The lactose in the milk is converted to lactic acid, which lowers the pH. The production of yoghurt is a relatively simple procedure. Milk, which can be fortified with milk powder to give a thicker product, is pasteurized, cooled and inoculated with starter bacteria, which ferment the milk, causing it to clot or gel.
