1. The following statement is similar to those you might see on exams. Write a paragraph of 3-5 sentences describing 1) whether
yanalaym [24]

Answer:

The oxygen dissociation curve represents the percentage saturation of Hb with oxygen at different partial pressure of oxygen. The different partial pressures gives sigmoid shapes to the curve. When this curves shifts to right, it  indicates  low affinity or binding of oxygen by the Hb. it also indicates the unloading or releases of Oxygen by Hb molecules at condition of low pressure. e,g in the muscles during strenuous exercise.However, when the curve shifts to the left, this indicate high affinity for oxygen, great binding, at high partial pressure of oxygen.e,g in the lungs to take oxygen and releases CO2.

Therefore in this scenario, the statement -. <u>During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right.</u> is correct. because oxygen is needed by the muscles therefore ,oxygen should be less binded by Hb,  decrease affinity and easily unloaded to muscles.

<u>The statement </u>This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 into hemoglobin in the lungs is wrong.

As explained above the rightwards shift indicated low affinity of Hb for oxygen(unloading)and  favours unloading at the muscles because during strenuous exercise the partial pressure of oxygen is very low(but that of CO2 high) in the muscles which favours low oxygen molecules  binding by Hb, and easy release to respiring cells.

Which of the following cell organelles are directly responsible for making and packaging proteins A) Mitochondria, Golgi complex
viktelen [127]
<h2>Answer:</h2>

The correct sequence of organelles involved in making and packaging of proteins is option C: ribosomes, endoplasmic reticulum, and Golgi complex.

<h3>Explanation:</h3>
  1. The protein synthesis which is the translation of mRNA is done on <u>ribosomes.</u>
  2. As the protein is produced then it goes for modification in the <u>endoplasmic reticulum.</u>
  3. After some modifications proteins are packed into vesicles for the intercellular and intracellular transport.
  4. This packing is done in <u>Golgi apparatus.</u>

During anaerobic respiration food molecules are _____________ oxidised, while during aerobic respiration they are ______________
monitta
Respiration using oxygen to break down food molecules is called aerobic respiration. 'Aero' means air, which contains oxygen, leading to the name aerobic respiration. Glucose is the molecule normally used for respiration - it is the main respiratory substrate. Glucose is oxidised to release its energy, which is then stored in ATP molecules.

The word equation for aerobic respiration is:

glucose + oxygen → carbon dioxide + water (+ ATP made)

You need to be able to recognise the chemical formulas:

C6H12O6 + 6O2 → 6CO2 + 6H2O
