Fetuses who were more active during the last trimester of the pregnancy became 2 year olds who were less fearful when interacting with an unfamiliar adult in a laboratory, and those with one year knew how to handle frustration better than those who were less active during the last trimester.
Answer:
Pyruvate is turned to lactate via a process called fermentation
Explanation:
Pyruvate is the product of the initial stage of cellular respiration called GLYCOLYSIS. Pyruvate is produced in the cytoplasm where glycolysis occurs. The fate of pyruvate i.e. what will eventually happen to pyruvate, is determined by the presence or absence of oxygen.
In the absence of oxygen i.e. anaerobic condition, pyruvate is converted into lactate in a process called FERMENTATION. The NADH produced during glycolysis is reoxidized to form NAD+ in the process.
The enzyme will be transported to either the cytoplasm or the mitochondria to perform the functions.
<h3><u>Explanation:</u></h3>
Cellular respiration is the process by which a living cell burns nutrients like glucose, fats, or even proteins to produce energy molecules namely ATP to perform its daily works. This cellular respiration, which is mainly aerobic, takes place both in cytoplasm and mitochondria.
The glycolysis part of the cellular respiration takes place in the cytoplasm. The enzymes that take part in the glycolysis cycle reaches to cytoplasm from ribosome to perform.
But both the Kreb's Cycle and the Electron Transport chain take place in mitochondria. Kreb's Cycle takes place in mitochondria matrix and ETC takes place in inner mitochondrial membrane. Although ETC isn't a enzymatic process, Kreb's Cycle is fully enzymatic and the enzymes reaches from ribosomes inside mitochondria by transporters.
Answer:
D) the thylakoid and mitochondrial inner membranes.
Explanation:
Electron transport chain in plant cells is used for extracting sunlight energy via redox reactions through the process of photosynthesis. This process occurs in chloroplast (thylakoid membrane), where light energy is transformed into chemical energy, that leads to the conversion of water to oxygen and NADP+ to NADPH with transfer of H+ ions across chloroplast membranes. Formed H+ gradient is used for the ATP synthesis.
In all eukaryotes, including plants, electron transport chain is located in the inner mitochondrial membrane where it serves as the site of oxidative phosphorylation (production of ATP) through the action of ATP synthase.
