Cell Metabolism

Yes, some cells can have only one mitochondrion, though this is relatively uncommon. For instance, certain unicellular organisms, like some types of yeasts or bacteria, may contain a single mitochondrion, while specialized cells in multicellular organisms may also exhibit a very low number of mitochondria. However, most eukaryotic cells typically contain multiple mitochondria to meet their energy demands.

stomata are found only in plants cells, but mitochondria are in both plant and animal cells. remember, they both perform cellular respiration, which occurs in the mitochondria

Yes, hormones are essential for normal metabolism as they influence the rate of metabolic processes in the body. Hormones like insulin, thyroid hormones, and cortisol play key roles in regulating metabolism, including energy production, storage, and utilization. Imbalances in hormone levels can lead to metabolic disorders.

Metabolic reactions in cells can be categorized into two main types: catabolic and anabolic reactions. Catabolic reactions involve the breakdown of complex molecules into simpler ones, releasing energy, as seen in cellular respiration where glucose is oxidized to produce ATP. Anabolic reactions, on the other hand, involve the synthesis of complex molecules from simpler ones, such as the formation of proteins from amino acids or the synthesis of glucose through photosynthesis in plants. Together, these reactions facilitate energy production, growth, and maintenance of cellular functions.

Mitochondria are often referred to as the "powerhouses" of the cell because they convert energy from nutrients into adenosine triphosphate (ATP) through a process called cellular respiration. This process involves glycolysis, the citric acid cycle, and oxidative phosphorylation, where glucose and oxygen are used to produce ATP, carbon dioxide, and water. During this conversion, chemical energy from food molecules is transformed into a usable form of energy (ATP) through the electron transport chain and chemiosmosis. This efficient energy conversion is essential for powering various cellular activities.

They don't receive nutrients from outside the body but from very small capillaries or even by simple diffusion if they are rather close to the skin.

Cytoplasm can be considered . It processes glucose to pyruvate

Mitochondria get glucose as pyruvic acids. It is processed by cytoplasm

The process of cellular respiration extracts the energy found in glucose.

Competitive inhibitor is a substance that competes directly with a normal substrate for an enzymatic-binding site of an enzyme. Such an inhibitor usually resembles the substrate to the extent that it specifically binds to the active site of the enzyme but differs from it so as to be unreactive and therefore there will be no catalytic reaction. Some examples are: methotrexate that is competitive inhibitor of dihydrofolate reductase, and malonate which structurally resembles succinate (that is converted to fumarate by succinate dehydrogenase during the citric acid cycle) but cannot be dehydrogenated.

During initiation phase of protein synthesis , most important thing formed is initiation complex .

Metabolism refers to all the chemical reactions that occur in the body to sustain life. Enzymes are biological molecules that speed up these chemical reactions by acting as catalysts. Essentially, enzymes help regulate and facilitate the metabolic processes in the body by increasing the rate at which reactions occur.

There is a balanced equation for glycolysis occurring in the mitochondria. The equation is glucose + 2ADP 2 + 2Pi + 2NAD --> 2ATP + 2NADH + 2 pyruvate.

Protein targeting in the cell is carried out via endoplasmic reticulum (ER) and mainly exported by Golgi apparatus (through vesicles). Proteins that have signal sequences will be destined to the nucleus and other organelles. Secretion of proteins to the cell membrane and out of cell by secretory vesicles.

Body will not get enough energy. So it will malfunction

That is to store energy. It is the universal currency of enegy

Animals are aerobic eukaryotic organisms. Aerobic organisms are those which get their energy by chemically breaking down molecules using oxygen. Eukaryotic organisms are those with cells that have internal organelles, particularly a nucleus. All aerobic eukaryotes produce energy within the mitochondria of their cells.

Yes, it is the powerhouse of the cell.

Mitochondria are not green. Chloroplast are green.
