Answer:
Explanation:
The main function of the plasma membrane is to protect the cell from its surroundings. Made of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules it also regulates the movement of substances in and out of cells. Plasma membranes must be very flexible in order to allow certain cells, such as red blood cells and white blood cells, to change shape as they pass through narrow capillaries. Membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors, which then trigger intracellular responses. Some viruses, such as Human Immunodeficiency Virus (HIV), can intercept these receptors to get into the cells, causing infections.

Answer: Cellular respiration is the process by which microorganisms obtain the energy available in carbohydrates. They take the carbohydrates into their cytoplasm, and through a complex series of metabolic processes, they break down the carbohydrate and release the energy. The energy is generally not needed immediately, so it is used to combine ADP with phosphate ions to form ATP molecules. During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons. This oxygen gas is identical to the oxygen gas given off in photosynthesis.
Explanation:
Answer:
Aerobic respiration;this is the process of breaking down of glucose <u>with Oxygen</u> to generate energy as ATPs in living cells
Location- Matrix and inner membranes of mitochondria
Energy source_oxidative phosphorylation of glucose
Waste product-water( oxygen accept the final electron to form water)
.
38 ATPs from 1 glucose molecule
Explanation:
Photosynthesis; this is the process of reducing C02 with hydrogen ion, from water i<u>n the presence of sunlight , enzymes and green pigment chlorophyll</u> to form <u>glucose</u>
Location- stroma and thylakoid membranes of chloroplast
Energy source-photo-phosphorylation(sunlight)
Waste product-Oxygen
18ATPs
Answer: The key direct impact of mining on forest ecosystems is the removal of vegetation and canopy cover. Indirect impacts include road-building and pipeline development, which may result in habitat fragmentation and increased access to remote areas.
