The rate of a physical or chemical process

Nady [450]

Answer:

(A) rate=

Explanation:

The rate of chemical is a measure of the speed of a chemical reaction.

The measurement of the reaction rate is based on the disappearance of a reactant or appearance of a product with increasing reaction time.

Reaction rate is usually expressed in terms of a change in concentration of the chosen reactant or product per unit of time.

During a reaction, the concentration of the reactant decreases exponentially with time while that of a product increases exponentially with time.

Reaction rate = $\frac{change in concentration of a reactant/product}{Time taken}$

Which describes an oxidation reaction that occurs during cellular respiration?

Yuri [45]

Answer: <u>Option 4; Oxygen gains electrons and hydrogen to form water. </u>

Respiration is a process where glucose is used and energy is released stored in this molecule. Oxygen is used during respiration as well and it gains the electrons and hydrogen to form water. And, gain of electrons is an oxidation reaction. So answer is option 4.

Since, oxygen is consumed during respiration, option 1 is incorrect.

Loss of electrons is reduction, so option 2 is also incorrect.

Glucose is used in respiration, thus option 3 is incorrect.

A student noticed that the freshwater plant, Elodea, produced bubbles when placed in direct light. What could the student most l

erastovalidia [21]

Explanation:

-The increased light intensity increased the rate of photosynthesis.

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water. Since photosynthesis is rate limited, the rate of energy intake can be increased in order to speed up photosynthesis, by speeding up photolysis.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

These end products, namely O2 and glucose are then used in respiration...

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

The CO2 and H2O produced as waste in respiration can then be incorporated at the beginning of photosynthesis. Thus the reactions are cyclic- they feed into each other.

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Respiration and photorespiration both utilize oxygen for;

the production of ATP via the oxidization of pyruvate;
and the oxygenation of the molecule Ribulose 1,5-bisphosphate (RuBP), an organic molecule also used in photosynthesis, to form 3-PGA + phosphoglycolic acid,

∴ the rate of CO2 usage for photosynthesis where O2 is produced, outpaces the rate of O2 use in respiration and photorespiration.

Three gel cubes similar to those from the previous

marta [7]

Answer:

These gel cubes can be thought of as representing individual cells. As the cubes interact with their surroundings based on the amount of surface area and volume they have, the efficiency movement of substances in and out of cells depends on the two attributes as well. Greater surface area will mean more efficient rates of diffusion, which implies a smaller surface area to volume ratio is ideal for a biological cell.
