Cellular Respiration in Plants — Flashcards

Answer

Cellular respiration is a catabolic, enzyme-mediated process in which complex organic compounds like carbohydrates, fats, and proteins are broken down to release energy. This energy is used to produce…

Answer

Cells need energy for essential functions like uptake of nutrients, cell division, growth, repair, and movement. This energy comes from breaking down food molecules through cellular respiration. Even …

Answer

Aerobic respiration is the process of breaking down glucose in the presence of oxygen to produce carbon dioxide, water, and a large amount of ATP (38 molecules per glucose). It occurs in the cytoplasm…

Answer

Anaerobic respiration is the breakdown of glucose without oxygen. It results in incomplete oxidation of food and produces only 2 ATP molecules per glucose. The end products are either lactic acid or e…

Answer

Glycolysis is the first step of cellular respiration where one molecule of glucose (6C) is broken down into two molecules of pyruvic acid (3C) in the cytosol. It does not require oxygen and produces a…

Answer

Glycolysis occurs in the cytosol. One glucose molecule is converted into two pyruvic acid molecules. It uses 2 ATP molecules initially but produces 4 ATP and 2 NADH, resulting in a net gain of 2 ATP a…

Answer

In aerobic respiration, pyruvic acid enters the mitochondria and undergoes oxidative decarboxylation. Each pyruvic acid molecule is converted into acetyl Co-A and CO₂, releasing one NADH molecule. Thi…

Answer

The Krebs cycle, also known as the citric acid cycle or TCA cycle, is a series of reactions in the mitochondrial matrix where acetyl Co-A is completely oxidized to CO₂ and water. It produces 3 NADH, 1…
