What two things help cells grow and live?

1. What promotes cell growth?

A growth factor is a naturally occurring substance capable of stimulating cell proliferation, wound healing, and occasionally cellular differentiation. Usually it is a secreted protein or a steroid hormone. ... Examples are cytokines and hormones that bind to specific receptors on the surface of their target cells.

2. what helps cells grow? For a typical dividing mammalian cell, growth occurs in the G1 phase of the cell cycle and is tightly coordinated with S-phase (DNA synthesis) and M phase (mitosis). The combined influence of growth factors, hormones, and nutrient availability provides the external cues for cells to grow.

oxygen & organelles

Explanation:

Once we are grown up, many cells mature and become specialised for their particular job in the body and they don't reproduce so often. But some cells, such as skin cells or blood cells are constantly dividing. When cells become damaged in any way or die, the body produces new cells to replace them. This process is called cell division.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
