Answer: Enzyme is a special kind of protein which conducts the catalysis of the reaction and speed up the rate of the reaction.
Explanation:
The change in shape of the enzyme will distort or change the shape of the active site of the enzyme thus the enzyme will not be able to bind to the specific substrate and no enzyme substrate complex will be formed so the enzyme will become non-function and will not conduct the catalysis of the reaction. Hence, no product will be formed as no reaction will occur. The high pH and temperature will distort the shape of the enzyme and the active site of the enzyme.
Changes in pH and temperature affect enzymatic activity. Any deviation from the optimum pH level or an increase of temperature over the optimum level denaturalizes the enzyme, and loses its catalytic activity.
----------------------------------
Enzymes, like all proteins, are polypeptidic molecules. They need to get an accurate tridimensional structure to accomplish their function.
There is a limited temperature and pH level at which they lose that structure and denaturalize.
• pH changes
The most accurate configuration for the best catalytic performance depends on the charge of the lateral chains and the environmental pH.
Enzymes have ionizable chemical groups in the lateral chains of their amino acids.
Depending on the environmental pH, these groups will have a positive, negative, or neutral charge.
There is an optimum pH level at which enzymes get the best configuration to accomplish their functions.
Most enzymes are sensitive to any change in pH, which might drastically affect their activity.
So every enzyme has its optimum pH level, and any slight deviations will cause the enzyme denaturalization, hence, its activity loss.
• Temperature changes
In general, the increase in temperature accelerates chemical reactions.
For every 10ºC of temperature increase, the reaction velocity duplicates.
The optimum temperature is the range in which the enzyme expresses its highest activity rate.
⇒ When the environmental temperature is lower than the optimum, there is a slow enzymatic activity.
⇒ When the temperature exceeds the optimum point, the enzymatic activity sharply decreases. It denaturalizes the enzyme. Over this level, the reaction velocity is counteracted by the loss of the catalytic activity due to denaturalization. Enzymatic activity decreases until it completely annulates.

While frying some eggs on a frying pan, a friend points to the change that happens to the egg white, which contains a protein called albumin. Your friend explains that if the conformation of a protein changes, it will no longer have the same properties and will lose its ability to function. Do you agree or disagree with your friend? What happened to the albumin?
EXPLAIN
Answer:
Yes because when subject to high heat, the proteins change into varying proteins, which is a chemical change. The heat causes denaturation of the albumin, which hardens and causes the change in color. The protein, when heated, untangle and they will mesh. This will trap the surrounding water, and cause the change in color.

the Krebs cycle occur(s), breaking down pyruvic acid into carbon dioxide in a series of reactions.
Explanation:
The innermost compartment of a mitochondrion is filled with a matrix. It is the site for the Krebs cycle. Here the pyruvic acid is broken down into carbon dioxide.
What is the Krebs cycle?The primary source of energy for cells and an essential component of aerobic respiration is the tricarboxylic acid (TCA) cycle, sometimes referred to as the Krebs or citric acid cycle. The cycle converts the acetyl coenzyme A (acetyl CoA) chemical energy into the reducing force of nicotinamide adenine dinucleotide (NADH).
The TCA cycle is a component of the broader glucose metabolism, which involves the oxidation of glucose to produce pyruvate, which is then further oxidized and reaches the TCA cycle as acetyl-CoA.
The cycle's half of intermediates also serves as the starting point for pathways that lead to significant molecules such as fatty acids, amino acids, or porphyrins. The integrity of the cycle is compromised and the cycle ceases to operate when any of these intermediates are so diverted. Only if the deflected intermediate or a succeeding intermediate that contributes to oxaloacetate can be replaced by anaplerotic (refilling) processes can vital energy production be restarted.
Therefore, the innermost compartment of a mitochondrion is filled with a matrix. It is the site for the Krebs cycle. Here the pyruvic acid is broken down into carbon dioxide.

Suspended in the fluid stroma of chloroplasts are
a.
cristae that provide energy.
numerous mitochondrial membranes.
b. stacks of thylakoids called grana. d. organelles called eukaryotes.
Stacks of thylakoids called grana are suspended in the fluid stroma of chloroplasts. Therefore, option (B) is correct.
Plants and other chloroplast-containing organisms transform sunlight into chemical energy through photosynthesis. The fluid stroma in plant cells' chloroplasts helps this process. The gel-like stroma surrounds the thylakoid membranes.
Chlorophyll-containing chloroplast thylakoids are membrane-bound. Light-dependent processes, the first stage of photosynthesis, collect light energy with these pigments. Grana boost light absorption by stacking thylakoids
In light-dependent reactions, thylakoid membrane chlorophyll molecules absorb light energy. ATP and NADPH, which are needed for the next stage of photosynthesis, are produced from this energy.
The fluid stroma around the thylakoid membranes includes enzymes, chemicals, and ions for dark processes and the Calvin cycle. ATP and NADPH from thylakoids convert carbon dioxide into glucose and other organic molecules in the Calvin cycle. Therefore, option (B) is correct.

A student observes that a plant has droopy leaves and stems and infers that the rate of photosynthesis has slowed in the plant. Which statement provides evidence to support the student's inference?
Answer:
The water pressure in the plant's vacuole is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis.
Explanation:
The water pressure in the plant's vacuole is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis. The water pressure in the plant's ribosomes is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis. The water pressure in the plant's vacuole is low, and without water, the mitochondria cannot convert carbon dioxide to glucose during photosynthesis. The water pressure in the plant's ribosomes is low, and without water, the mitochondria cannot convert carbon dioxide to glucose during photosynthesis.The correct answer would be that the water pressure in the plant's vacuole is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis.
Photosynthesis generally requires water as one of its reactants in the formation of carbohydrates for plant nutrition.

D. The water pressure in the plant's ribosomes is low, and without water, the
mitochondria cannot convert carbon dioxide to glucose during photosynthesis.
With which cellular process are ribosomes directly involved?
The correct option is C.
Explanation:
When a plants vacuole has no pressure and water, the leaves and stems will drop because vacuole is an organelle that serve as storage for food nutrients and water . When a plant has no water for a long period of time, the vacuole will lose water, which will make the cell to lose shape, and the leaves and stems will wilts and drop ,and this make the mitochondria not to be able to convert chemical energy in glucose using carbondioxide and water to Energy or ATP because there is no supply of water or there is water lose.
