În procesul respiratiei anaerobe:
Correct Answer
B. Se elibereaza o cantitate redusa de energie
Explanation
In the process of anaerobic respiration, only a small amount of energy is released. This is because anaerobic respiration occurs in the absence of oxygen, and oxygen is required for the complete oxidation of organic substances, which results in the release of a larger amount of energy. In anaerobic respiration, only partial oxidation of organic substances occurs, leading to the production of smaller amounts of energy.

La mamifere, o expiratie normala presupune:
Correct Answer
B. Cresterea presiunii intrapulmonare
Explanation
During a normal expiration, the diaphragm and intercostal muscles contract. This contraction leads to an increase in intrapulmonary pressure. As a result, the volume of the thoracic cavity decreases, causing the air with carbon dioxide to be expelled from the lungs. Therefore, the correct answer is the increase in intrapulmonary pressure.
13.
În respiratia aeroba are loc:
Correct Answer
D. Stocarea energiei sub forma de ATP
Explanation
În respirația aerobă are loc stocarea energiei sub forma de ATP. Respirația aerobă este procesul prin care organismele produc energie prin oxidarea completă a substanțelor organice în prezența oxigenului. Această oxidare eliberează energie care este captată și stocată sub forma de ATP (adenozin trifosfat), o moleculă care furnizează energie pentru majoritatea reacțiilor celulare. Astfel, stocarea energiei sub forma de ATP este unul dintre rezultatele principale ale respirației aerobe.
14.
Prin fermentatie, drojdiile produc:
Correct Answer
B. Alcool etilic
Explanation
During fermentation, yeast produces alcohol, specifically ethyl alcohol. Fermentation is a metabolic process where yeast breaks down sugars, such as glucose, and converts them into alcohol and carbon dioxide. Ethyl alcohol, also known as ethanol, is the type of alcohol commonly found in alcoholic beverages. It is produced by yeast as a byproduct of their metabolic activity. Therefore, the correct answer is alcool etilic (ethyl alcohol).
15.
Respiratia aeroba:
Correct Answer
A. Are loc in prezenta oxigenului
Explanation
Respirația aerobă are loc în prezența oxigenului. Aceasta este o formă de respirație în care organismele utilizează oxigenul pentru a descompune moleculele de glucoză și a produce energie. Procesul implică o serie de reacții chimice în mitocondrii, care rezultă în eliberarea de dioxid de carbon și apă, precum și producerea de ATP - principala sursă de energie pentru celule. Prin urmare, prezența oxigenului este esențială pentru a permite organismelor să efectueze respirația aerobă și să producă energie eficient.

21.
În timpul inspiratiei:
Correct Answer
C. Sternul se indeparteaza de coloana vertebrala
Explanation
During inspiration, the diaphragm muscle relaxes, causing the base of the thoracic cavity to rise. This expansion of the thoracic cavity increases the volume of the lungs, creating a decrease in pressure. As a result, air flows into the lungs. The sternum, which is connected to the ribs, moves upwards and away from the spinal column, allowing for further expansion of the thoracic cavity and facilitating the inhalation of air.
22.
Respiratia anaeroba:
Correct Answer
A. Este prezenta la bacterii si ciuperci
Explanation
The correct answer is "este prezenta la bacterii si ciuperci" because the statement accurately describes anaerobic respiration.
