Answer: The answers are as follows:
Where does the Calvin cycle occur and does it need light?
Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).
Where does photosynthesis get its energy to start?
The whole process of photosynthesis is a transfer of energy from the Sun to a plant. In each sugar molecule created, there is a little bit of energy from the Sun, which the plant can either use or store for later.
What is the chemical equation for cellular respiration?
The equation for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H20 + energy (Glucose + Oxygen yields Carbon Dioxide + Water + Energy) You may notice that the equation for cellular respiration is the opposite of the equation for photosynthesis.
What are the reactants and products of lactic acid fermentation? What is the basic equation?
The simple equation for lactic acid fermentation is glucose ---glycolysis---> 2 pyruvate ---fermentation--> 2 lactic acid. That is to say that glucose is broken down by glycolysis into 2 pyruvates, and then those pyruvates are fermented to produce 2 lactic acid molecules.
How is citric acid formed in the Krebs cycle?
The Krebs cycle itself actually begins when acetyl-CoA combines with a four-carbon molecule called OAA (oxaloacetate) (see Figure above). This produces citric acid, which has six carbon atoms. This is why the Krebs cycle is also called the citric acid cycle.
What are the steps in cellular respiration?
There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation. Glycolysis takes place in the cytosol, the citric acid cycle occurs in the mitochondrial matrix, and oxidative phosphorylation occurs on the inner mitochondrial membrane.
The energy for glycolysis comes from which molecule?
Glycolysis is a series of reactions that extract energy from glucose by splitting it into two three-carbon molecules called pyruvates.
During which step of cellular respiration is carbon dioxide released?
The stage of cellular respiration in which carbon dioxide release takes place is the citric acid cycle. Aerobic cellular respiration has three steps, glycolysis, the citric acid cycle, and the electron transport chain.
What are the products and reactants of cellular respiration?
During cellular respiration, the reactants—glucose (sugar) and oxygen—combine together to form new products: carbon dioxide molecules and water molecules.
Explain how ectotherms and endotherms regulate their body temperature.
Endotherms use internally generated heat to maintain body temperature. Their body temperature tends to stay steady regardless of the environment. Ectotherms depend mainly on external heat sources and their body temperature changes with the temperature of the environment.
How do humans control their body temperature using ATP?
The muscle contractions of shivering release heat while using ATP. The brain also triggers the thyroid gland in the endocrine system to release thyroid hormone, which increases metabolic activity and heat production in cells throughout the body.
In 3-5 sentences explain how the environment would affect the photosynthetic process of a rainforest plant versus a desert plant. Consider the amount of sunlight and water available in each environment.
The environmental factors that would be more important to a rainforest plant would be sunlight and carbon dioxide. This is because rainforests are shadier and there would be less sunlight for the plant to get, which could cause the plants to get taller in order to reach the sunlight. However, in the desert, the plants would be more dependent on water and carbon dioxide.
Dragonflies are flying insects. In the summer, dragonflies can be seen perched on tree branches in an obelisk pose (i.e., a handstand position with the tip of their abdomen pointing upward). In 3–5 sentences, describe how dragonflies might control their body temperature and give reasons for why they might perch in this pose.
The powered flight regulates body temperature and obelisk posture helps to prevent overheating due to the sun. Dragonflies control their body temperature with the help of controlling metabolic heat production by alternately using powered flight as well as controlling heat loss by changing the circulation between the thorax and abdomen. The dragonflies raised their abdomen until its tip pointed to the sun in order to minimize the surface area exposed to solar radiation so that powered flight regulates body temperature and obelisk posture helps to prevent overheating due to the sun.
