Answer:
The options
A)Damage to cellular mitochondria
B)Increased ATP levels
C)Activation of the p53 protein
D)Apoptosis
The CORRECT ANSWER IS D
D)Apoptosis
Explanation:
The extrinsic pathway of apoptosis includes extracellular signaling proteins which adhere to cell surface molecules known aa death receptors which in turn activates apoptosis.
The aftermath activates endonucleases prompting division of DNA and ultimately cell death.
Apart from the TNF and Fas ligand, primary signaling molecules also promotes the extrinsic pathway, examples of such are the TNF-related apoptosis-inducing ligand (TRAIL); the cytokineinterleukin-1 (IL-1); and lipopolysaccharide (LPS), the endotoxin located in the outer cell membrane of gram-negative bacteria while the activation of the p53 protein, and decreased ATP levels in the intrinsic pathway results in DNA damage.
Out of the following given choices;
a) The amount of oxygen produced
b) The rate of ATP synthesis by ATP synthase in the chloroplast
c) The rate at which NADPH is produced
d) The rate at which the protons are transported into the thylakoid
The answer is; A
The photosystem captures energy from sunlight and uses it to split a water molecule. After splitting the water molecule (by taking an electron), the protein complex transports the electron to plastoquinone. The splitting of water molecules results in evolving of oxygen molecules. The hydrogen is what is used to reduce carbon dioxide to glucose.
Answer:
D
Explanation:
The cuticle of a plant helps protect its aerial epidermis from things like environmental stresses and desiccation.
