The answer to this question would be: oxygen
The presence of oxygen allows the cell to do the aerobic reaction. Using in metabolism will result in a much higher number of ATP produced.
When there is no oxygen, the cells make energy using the anaerobic reaction that gives a low number of ATP.
Answer:
2) is chemically specific
Explanation:
Enzymes are organic catalysts which speed up or control chemical reactions in cells. Enzymes are specific in the reactions they catalyze. An enzyme will only catalyze one specific reaction or a group of closely related reaction. Enzyme salivary amylase found in the mouth only hydrolyses starch into maltose.
Answer:
cell wall, cell membrane, cytoplasm, vacuole, ER and nucleous
Explanation:
The steroids are produced by the Smooth endoplasmic reticulum.
The cells, which are involved in the secretion of the steroid molecules have an abundant number of the smooth endoplasmic reticulum, which is abbrevated as SER.
The cells present in the ovary and the testis have a large number of smooth endoplasmic reticulum. The abundant number of smoothe endoplasmic reticulum allow them to produce a large amount of steroid molecule to produce the steroid hormones estrogen and testosterone.
Hence, in this case, the ovarian cells would have a large number of SER.
Innate: keratinized epithelium
stratified squamous epithelium hypodermal areolar connective tissue antigen presenting cells major histocompatibility complexes complement (antibody -dependent pathway )
Innate or non-specific response is the first defense against invaders. Components of this response include physical (e.g. skin . mucosa) and chemical barriers against pathogens and cells such as Natural Killer cells, macrophages, neutrophils, dendritic cells, mast cells, basophils, eosinophils. Innate response reacts immediately.
Adaptive: immunoglobulin plasma cells agglutinin
helper t cells memory t cells cytotoxic t cells cd4+cells
t lymphocytes
Adaptive immune response or specific response is specific to the pathogen presented and mediated by lymphocytes, B and T cells. Adaptive immune response creates immunological memory after the first, initial l response to a specific pathogen which leads to enhanced response.
