a. chloroplast
b. mitochondria
c. nucleus
d. ribosome
e. rough endoplasmic reticulum
f. lysosome
value: 7
what is the function of nadh?
a. energy in the food we eat
b. the chemical use by plants to make fruit
c. an electron transporter
d. waste product of aerobic cellular respiration
e. waste product of fermentation
value: 7
fermentation requires glycolysis
true
false

Explanation:

1. Mitochondria are the power - houses of the cell where most of the reactions of aerobic cellular respiration occur. Chloroplasts are for photosynthesis, the nucleus contains genetic material, ribosomes are for protein synthesis, rough endoplasmic reticulum is related to protein and lipid synthesis, and lysosomes are for digestion.
2. NADH is an electron transporter in cellular respiration, carrying high - energy electrons to the electron transport chain.
3. Fermentation starts with glycolysis, which breaks down glucose into pyruvate. Then, in the absence of oxygen, pyruvate is further processed in fermentation pathways.

Answer:

1. b. Mitochondria
2. c. an electron transporter
3. True
