Question

Enumerate the differences between the following (chemical equation also expected).

i) Aerobic and anaerobic respiration.

ii) Photosynthesis and respiration

Answer 1

Explanation:

Aerobic and anaerobic respiration.

Differences. As we touched on, the main difference 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 created.

Photosynthesis and respiration

The main difference between photosynthesis and cellular respiration is that photosynthesis is an anabolic process, where the synthesis of organic compounds occurs, storing energy whereas cellular respiration is a catabolic process, where the stored organic compounds are utilized, producing energy.

Answer 2

Answer:1 - Aerobic respiration takes place in presence of oxygen whereas anaerobic respiration takes place in the absence or low amount of oxygen.

2 - The process of conversion of light energy into chemical energy which is used to prepare sugar in presence of carbon-dioxide is called photosynthesis. It is an anabolic process. Whereas respiration is the process of breakdown of complex food into simple one and produce energy. It is a catabolic process.

Explanation:

1 - First glucose is converted into pyruvate in the cytoplasm of a cell. If sufficient amount of oxygen is present then respiration takes place in mitochondria and pyruvate is converted into carbon-dioxide,water and energy,if the oxygen is not sufficient then anaerobic respiration takes place in cytoplasm and pyruvate gets converted into lactic acid or ethanol and energy..

2 - photosynthesis

Carbon dioxide + water (in presence of chlorophyll and sun light) give glucose+ water + oxygen

Respiration

Glucose + oxygen gives carbon-dioxide +water + energy.
