8) Each time a molecule of glucose is completely oxidized via aerobic respiration, how many oxygen (O2) molecules are required?

11Alexandr11 [23.1K]

Answer:

C) 6

Explanation:

The balanced equation for aerobic cellular respiration is:

C₆H₁₂O₆ + 6 O₂ ----> 6 CO₂ + 6 H₂O + Energy (ATP)

For each glucose molecule that's oxidized, 6 oxygen molecules are used in order to produce ATP. Carbon dioxide and water are byproducts of aerobic respiration..

1.Write the equation for light dependent reaction of photosynthesis

Annette [7]

Answer:

1. The overall chemical equation of the light-dependent reactions is given below:

12 H₂O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll ----> 6 O₂ + 12 NADPH + 18 ATP

2. The overall chemical equation for the light-independent reactions of the Calvin cycle is given below :

3 CO₂+ 6 NADPH + 5 H₂O + 9 ATP → glyceraldehyde-3-phosphate (G3P) + 2 H+ + 6 NADP+ + 9 ADP + 8 Pi

Explanation:

1. The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH which are used light-independent reactions to drive the synthesis of sugar molecules from inorganic CO₂ and water. Light-dependent reactions takes place in photosystem I and II. Photosystem I and Photosystem II ( PS I and PS II) are the two biochemical systems, active in chloroplasts, that serve as sites of electron transfer reactions in photosynthesis. Energy from sunlight is used to split water which releases electrons and hydrogen atoms which are transferred to NADP+ to produce ATP and NADPH and oxygen is produced as a waste product.

The overall chemical equation of the light-dependent reactions is given below:

12 H₂O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll ----> 6 O₂ + 12 NADPH + 18 ATP. Note that Pi refers to inorganic phosphate

2. The Calvin cycle refers to the light-independent reactions in photosynthesis. It occurs in three stages.

Stage 1 (Carbon fixation): In this first stage of the Calvin cycle, light-independent CO₂ is fixed by enzyme called ribulose bisphosphate carboxylase (RuBisCO) to ribulose bisphosphate (RuBP) to form glyceraldehyde-3-phosphate.

Stage2: ATP and NADPH are used to reduce 3-phosphoglycerate (3-PGA) into glyceraldehyde--phosphate (G3P). ATP and NADPH are used up in the process and are converted to ADP and NADP+, respectively.

Third stage: RuBP is regenerated, which enables the system to prepare for more CO2 to be fixed.

The overall chemical equation for the light-independent reactions of the Calvin cycle is given below :

3 CO₂+ 6 NADPH + 5 H₂O + 9 ATP → glyceraldehyde-3-phosphate (G3P) + 2 H+ + 6 NADP+ + 9 ADP + 8 Pi

As hominids evolved, their eyes increased in size and became more forward facing. Which of the following can be inferred from th

lisabon 2012 [21]

The answer is Hominids became more dependent on vision over time and less so on their other senses. <span>This statement is related to the general decrease in the importance of smell and the increasingly significant use of vision. The stereoscopic (three-dimensional) vision and the appropriate perception of the resulting depth enabled the development of visual acuity over time.</span>

Use the diagram for three question

Misha Larkins [42]

Answer:

a. Light provides the energy for the chemical reactions that take place during photosynthesis, and the table includes only matter, not energy.

Explanation:

Photosynthesis is the process by which plants and certain organisms produce their food (glucose). The photosynthetic process, which occurs in stages, uses LIGHT ENERGY from sun in the first stage called light dependent reaction.

LIGHT is pivotal to the process of photosynthesis as it serves as the energy source for the chemical reactions that synthesizes ATP and NADPH, which are products of the light stage of photosynthesis. However, based on the table in the attachment of this question, it only contains matter as reactants and products and not ENERGY.
