Answer:

K = 9.620 × 10⁻⁶

Explanation:

From the given information:

Temperature T= 6° C

= (273 + 6)K

= 279 K

The correct and well presentation of the reactions are:

1. Luciferin + O_2     ⇆     oxyluciferin + light   ΔG₁°

2. ATP                     ⇄   AMP + PP_i                  ΔG₂°  = -31.6 kJ/mol

The overall  ΔG° = -4.80 kJ/mol

Let's first determine the ΔG₁° for the equation (1)

ΔG° = ΔG₁° + ΔG₂°

- ΔG₁° = - ΔG° + ΔG₂°

ΔG₁° = ΔG° - ΔG₂°

ΔG₁° = ( -4.80 - (-31.6) ) kJ/mol

ΔG₁° = 26.8 kJ/mol

Using the formula:

ΔG° = -RTIn K

In \  K =\dfrac{-\Delta G^0}{RT} \\ \\ log \ K = -\dfrac{\Delta G^0}{2.303RT}

log \ K = -\dfrac{\Delta G_1^0}{2.303RT} \\ \\ log \ K = -\dfrac{26.8 \times 10^3 \ J/mol}{2.303\times 8.314 \ J/mol/K \times 279 \ K} \\ \\ log \  K =- 5.017

K = antilog (-5.017)

K = 9.620 × 10⁻⁶

Compare and contrast aerobic and anaerobic respiration. We need to discuss the following points: stages involved, locations in t
Tomtit [17]

Answer:

Differences between aerobic and anaerobic respiration is whether or not oxygen is present. . During aerobic respiration, carbon dioxide, water, and ATP are produced. During anaerobic respiration, lactic acid, ethanol, and ATP are create, aerobic os used when heart rate and breathing rate rise, anaerobic is used during the first 1-2 mins of exercise, occurs in the cytoplasm of cells, while aerobic occurs in the mitochondria of the cells,  glycolysis occurs in both,  both are respiration, and both create ATP

Which of the following are examples of positive feedback loops? (Choose all that apply)
aleksley [76]

The examples of positive feedback loops are as follows:

  1. contractions during the process of giving birth
  2. Blood clotting

<h3>WHAT IS POSITIVE FEEDBACK LOOP:</h3>
  • Positive feedback loop is that in which a change in a given direction causes additional change in that same direction.

  • The contractions during the process of giving birth is an example of positive feedback loop because the contractions further stretch the walls and continues until birthing occurs.

  • Also, the clotting of blood causes the stoppage of blood flow.

Therefore, the examples of positive feedback loops are as follows:

  1. contractions during the process of giving birth
  2. Blood clotting
