The process of can be defined as about 30 individual, sequential chemical reactions that form three metabolic pathways: one in the cytoplasm and two within the mitochondrion.

Cellular respiration

Explanation:

Cellular (aerobic) respiration is a process by which both autotrophic and heterotrophic organisms obtain energy by conversing adenosine diphosphate (ADP) to adenosine triphosphate (ATP). During this process, oxygen (O2) is combined with molecules obtained from the food, thereby releasing carbon dioxide (CO2) and water (H2O). Cellular respiration has three steps: glycolysis, the Krebs cycle, and the chain of electron transport: the first step (glycolysis) is carried out in the cytosol, while the last two take place in the mitochondria.

d is the answer

sorry if its wrong!

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
